Grammar a Day - Level 1 - なり (nari)

なり (nari) - As soon as

--- Notes ---
Verb(辞書形) + なり

[AなりB] - B is often an unexpected or unusual thing.

--- Examples ---
彼は帰ってくるなり食事もせずに寝てしまいました。
As soon as he got home, he went to bed without eating.

彼はドアを開けるなり、靴をはいたまま部屋に入ってきた。
As soon as he opened the door, he walked in still wearing his shoes.

パーティー会場に入るなり、サムは食べ物めがけて突進した。
As soon as he got to the party, Sam made a bee line for the food.

ファンは、有名人と出くわすなり、彼にサインを求めた。
On encountering the celebrity, the fans asked for his autogaph.

教室に入るなり、先生は突然怒ったような口調で話しはじめた。
On entering the classroom, our teacher burst into angry speech.

入ってくるなり、彼は倒れた。
The instant he came in, he fell down.

--- Comments ---
My book says that this is for a strange or unexpected event.

X スイッチを入れるなり電気がついた。
O スイッチを入れると電気がついた。
O スイッチを入れるなり爆発が起きた。

However, my book says it is only used for Verb(辞書形)+なり, but I have
sometimes seen cases of Verb(た形)+なり from other sources. Does anyone
know which is correct? (contributor: blabby)

Verb(た形)+なり is used in a different way. It implies one movement is
continuing. 〜したまま。
会社を出たなり、いつまでも帰らない。He left the office and hasn't come
back.
彼女を見つめたなり、しばらくの間微動だにしなかった。He stared at her and
didn't move an inch for a while.
You can find better translations. (contributor: Miki)

that sounds like a totally different nari, so i created a new page for it:
[nari2] (contributor: dc)

Grammar a Day - Level 1 - 始末だ (shimatsuda)

始末だ (shimatsuda) - Unfortunately, (it has become ~)

--- Notes ---
Verb(辞書形) + しまつだ。

The result is always something bad.

Meaning: Finally, on top of that. Used to describe when something bad
becomes worse.

--- Examples ---
あの二人は犬猿の仲で、ちょっとしたことでも、すぐ口論になる始末だ。
Those two don't get along very well. Unfortunately, at the drop of a hat,
they start arguing.

友達に借金までするしまつだ。
Unfortunately, it has got to the point where he has to borrow money from
friends.

この始末は、今まで述べたとおりです。
Just as I said, it turned out like this!

離婚してうえに、首にまでなるしまつだ。
On top of getting divorced, I got fired from my job

--- Comments ---
I think this is similar to '〜してしまった' or
'〜ということになっちゃった'.
In my grammar book, there is no kanji but if you do a google search, 始末だ
comes up often.
I'm not very confident about example #5437... (contributor: blabby)

#5437 Do you mean 結末 ketsumatus instead of 始末? (contributor: Miki)

#5437 is copied exactly as I found it. I'm not quite sure about it because
it is not at the end of the sentence as all the other examples are. 結末
and probably even 結果 sound like they would be good in context.
(contributor: blabby)

In #5437,始末 means 'from the beginning to the end' whereas in all other
examples, 始末 is used to mean 'situation' or 'circumstances.'

Grammar a Day - Level 1 - とにかく (tonikaku)

とにかく (tonikaku) - in any case, anyway

--- Notes ---
often comes at the beginning of a sentence


see all these examples at ALC


--- Examples ---
それはとにかくとして、この問題はどうするの。
Leaving that aside, how do you intend to deal with this problem?

とにかく私に言えるのは
Anyway, all I can say is...

とにかく頼むからちょっと聞いてよ
Anyway I'm asking you to just listen for a minute

Anyway, I'm glad you were able to broach this difficult subject.

とにかく、私はあなたの意見には反対だ。
I am against your opinion in any case.

--- Comments ---
とにかく can be replaced by tomokaku ともかく. (contributor: Miki)

I would like to know more about the etymology of this expression. Does it
have anything to do with the Shogi game where two pieces are named 'to' and
'kaku'? (contributor: Nizar)

why is it every time when i clikc on the title the msg below will show.
Return to beginning of the Text Translation function. Unable to map
glossdic.xjdx!
(contributor: snoopycheng)

Nizar, tonikaku is not to do with 'to' and 'kaku' of Shogi game. とにかく
is used in hiragana by edo period. と of とにかく meant そのように、 かく
meant このように。 Tonikaku is sometimes write as 兎に角 but this is
phonetic equivalent. This is considered to come from Buddhism word
「兎角亀毛」. Rabbit doesn't have horns and turtle doesn't have hairs,
which was used when you talked about something doesn't exist. So this has
no relevance to current とにかく in meaning. BTW, in shogi, 「と金」 which
is another side of 「歩(ふ)」 is called と because the simplified form of
金 looks like と。 角(かく) is also called 角行(かくぎょう).
(contributor: Miki)

I have heard this word used in a lot of contexts where it couldn't mean
anyway, in any case. I asked some friends who had some difficulty
explaining it, but one seemed to say that it also has the meanings:
'quickly', 'with all haste' and maybe also 'naturally'. I also heard it
implies that some information given is generally known by everyone. Any
native speakers care to comment? (contributor: yookoso)

You have it wrong. とにかく急ごう means 'leaving all that aside, let's
hurry.' Thus, とにかく does not have a meaning of 'quickly' or 'naturally.'

Re Miki-san's comment, 角行 is pronounced かくこう.
(contributor: bamboo4)

Lesson Plan - Build A Submarine

Lesson Plan - Build A Submarine

LESSON PLAN MATERIALS:

·         Build a Submarine activity sheet

·         empty 16 or 20 oz. plastic soda bottle with hole in cap (the hole should be big enough to pass a flexible straw through)

·         three wide rubber bands

·         24 pennies

·         aluminum foil

·         adhesive tape

·         flexible straw

·         large tub of water

LESSON PLAN PROCEDURE: Build a Submarine activity sheet

1. Cut three holes in side of the soda bottle.

2. Stack the pennies into three piles containing 4, 8, and 12 pennies.

3. Carefully wrap stacks of pennies with foil.

4. Place a rubber band around the plastic bottle and slide it next to the closest hole. Position the other rubber bands next to the two remaining holes.

5. Place the four-penny stack under the rubber band closest to the bottle's top.

6. Place the eight-penny stack under the middle rubber band, next to the middle hole.

7. Place the 12-penny stack under the last rubber band (NOTE: The weights should be next to the holes NOT over them.)

8. Push the shorter end of the straw (about 1 inch) through the hole in the bottle's cap. Reattach the bottle cap to the bottle. Keep the flex section outside and bent upwards. Tape straw securely into place in bottle cap.

9. Lower the "submarine" into the water. Do not let long end of straw take in water.

10. Observe the action of the "sub" and record your observations.

11. When the sub stops sinking, blow into the straw.

12. Observe the action of the sub and record your observations.


LESSON PLAN QUESTIONS:

1. What makes your submarine sink?

2. What makes it surface?

3. After you learn the basic properties that make submersibles dive and surface. What is your soda bottle model missing that real submarines have to navigate underwater? Think of your sub as an underwater plane.

The Future of Submarines

The Future of Submarines

The evolution of future submarines for military use will be driven by the trend to use smaller, autonomous, and unmanned vehicles to perform missions both under and above the sea. Submarines of the future will be used for their inherent stealth to link and provide support to a deployed network of sensors and weapons. These deployed systems will act to increase the area over which the submarine performs its missions and improve its effectiveness in performing these missions, while reducing the threat to the submarine and its crew.

Modularization coupled with the development and use of off-board systems will allow a wide range of payloads to be employed by submarines. These remote sensors and weapons will include Unmanned Aerial Vehicles (UAVs); Unmanned Undersea Vehicles (UUVs); advanced cruise missiles; undersea acoustic and non-acoustic sensors and weapons; and new forms of submarine based systems for Anti-Submarine, Anti-Surface, and Anti-Air Warfare.

These capabilities combined with the submarine's advantage of being able to remain on-station and undetected for extended periods will multiply the effectiveness of these systems by adding the element of surprise and survivability.

The following timeline summarizes the evolution of submarine design, from the submarine's beginning as a human-powered warship to today's nuclear powered subs.

1578 <http://inventors.about.com/od/sstartinventions/a/Submarines_2.htm>

The first submarine design was drafted by William Borne but never got past the drawing stage. Borne's submarine design was based on ballast tanks which could be filled to submerge and evacuated to surface - these same principles are in use by today's submarines.

More Info <http://inventors.about.com/od/sstartinventions/a/Submarines_2.htm>

1620 <http://inventors.about.com/library/inventors/bldrebbel.htm>

Cornelis Drebbel, a Dutchman, conceived and built an oared submersible. Drebbels' submarine design was the first to address the problem of air replenishment while submerged.

The Colonial Army attempted to sink the British warship HMS Eagle with the Turtle. The first submarine to dive, surface and be used in Naval combat, its intended purpose was to break the British naval blockade of New York harbor during the American Revolution. With slight positive buoyancy, it floated with approximately six inches of exposed surface. Turtle was powered by a hand-driven propeller. The operator would submerge under the target, and using a screw projecting from the top of Turtle, he would attach a clock-detonated explosive charge.  More Info <http://inventors.about.com/od/sstartinventions/a/Submarines_3.htm>

Nuclear Propulsion Submarines - Admiral Hyman Rickover

Nuclear Propulsion Submarines - Admiral Hyman Rickover

In the 1950s a revolution in sub design occurred - the introduction of nuclear propulsion. With nuclear power the submersible torpedo boat of old became a true submarine - a ship with greater endurance than its human crew.

Hyman Rickover - Background

Admiral, Hyman Rickover, the Father of the Nuclear Navy, was born in Makow, Russia (which is now Poland) on January 27, 1900. At the age of six, he emigrated with his parents to the United States, settling in Chicago, Illinois. Hyman Rickover entered the U.S. Naval Academy in 1918 and was commissioned an ensign in June 1922.

Following sea duty aboard USS La Vallette (DD-315) and USS Nevada (BB-36), Hyman Rickover attended Columbia University, where he earned the degree of Master of Science in Electrical Engineering. From 1929 to 1933, he qualified for submarine duty and command aboard the submarines S-9 and S-48.

In June 1937, he assumed command of USS Finch. Later that year, he was selected as an Engineering Duty Officer and spent the remainder of his career serving in that specialty.

During World War II, Hyman Rickover served as Head of the Electrical Section of the Bureau of Ships and later as Commanding Officer of the Naval Repair Base, Okinawa. In 1946, he was assigned to the Atomic Energy Commission laboratory at Oak Ridge, Tennessee and, in early 1949, to the Division of Reactor Development, U.S. Atomic Energy Commission.

USS Nautilus

As director of the Naval Reactors Branch, Hyman Rickover developed the world's first nuclear powered submarine, USS Nautilus </od/weirdmuseums/ig/Submarine-Photo-Gallery/USS-Nautilus.htm> (SSN 571), which went to sea in 1955. In the years that followed, Hyman Rickover directed all aspects of building and operating the nuclear fleet.

Hyman Rickover - Awards

Hyman Rickover's numerous medals and decorations include the Distinguished Service Medal, Legion of Merit, Navy Commendation Medal, and the World War II Victory Medal. In recognition of his wartime service, he was made Honorary Commander of the Military Division of the Most Excellent Order of the British Empire.

Hyman Rickover was twice awarded the Congressional Gold Medal for exceptional public service. In 1980, President Jimmy Carter presented Admiral Rickover with the Presidential Medal of Freedom, the nation's highest non-military honor, for his contributions to world peace.

Hyman Rickover retired from the United States Navy on January 31, 1982, after over 63 years of service to his country and to 13 Presidents. His name is memorialized in the attack submarine USS Hyman G. Rickover (SSN 709) and Rickover Hall at the U.S. Naval Academy. Hyman Rickover died on July 8, 1986 and is buried in Arlington National Cemetery.

World War II Submarines

World War II Submarines

Both sonar and radar technology matured during World War II, and both were used by the Allies to combat German U-boats. Sonar and radar were also added to Allied submarines to warn of aircraft attack and counterattack from surface vessels. Since World War II sonar has been the most important of the submarine's senses. Hydrophones are the submarine's ears, and they listen for sounds from other ships and the echoes of sound waves transmitted from the submarine itself. See Photo: Typical WW II Submarine Layout </od/weirdmuseums/ig/Submarine-Photo-Gallery/WW-II-Submarine-Layout.htm>

Submarine Snorkels

During World War Two German submarine losses increased sharply as radar-equipped Allied aircraft attacked U-boats running on the surface recharging their batteries. To charge the batteries that powered the electric motors for submerged operations, all submarines had to surface to run their air-breathing diesel engines.

To counter the Allied radar threat the Germans perfected a Dutch device known as the snorkel. Using a snorkel a submarine could run its diesel engines and recharge its batteries while operating just below the surface. Air for the diesel engines was drawn into the submarine through the snorkel that was extended to the surface. To some extent the snorkel reduced vulnerability to detection and attack, but it protruded above the surface and could be detected by radar. The Germans introduced the snorkel too late in the war to make a difference.

Japan

Although the U.S. Navy still had a relatively small number of subs when World War Two broke out, this fact did little to dampen the spirits of American submariners. On January 7th, 1942, one month after the attack on Pearl Harbor, the USS Pollack (SS-179) sank a Japanese freighter off Tokyo Bay. It would be the first of many sinkings by U.S. submarines. When the figures were finally tabulated, it was found that American submarines sank five and one-half million tons of Japanese shipping, over half of the entire Japanese merchant fleet. U.S. subs accounted for about 60 per cent (over 1300 ships) of all Japanese merchant and warship tonnage sunk, yet the submarine strength at that time comprised less than two per cent of the entire U. S. Fleet.

The U.S. sub campaign deprived Japanese industry of raw materials and effectively shut down Japan's economy. The price of this success was high, 52 American submarines and over 3500 sailors remain on eternal patrol.

Greater Underwater Propulsion Program

Technological advancements like sonar, radar, and the snorkel came about as a result of the pressures of WW II, and the U.S. Navy applied these advances to improving its Submarine Force. In the late 1940s the Navy began the Greater Underwater Propulsion Program (Guppy </od/weirdmuseums/ig/Submarine-Photo-Gallery/Guppy-Type-Submarine.htm>), a modernization program for World War Two fleet-type submarines.

Under Guppy the fleet boats were streamlined by reducing the submarine's superstructure and removing deck guns. Snorkel masts were installed to allow Guppys to remain submerged while they ran their diesel engines and charged batteries. Finally, improved storage battery technology permitted longer submerged operations between battery charges. However, the Guppy program was evolutionary, a development of existing technologies

Military Application Submarines

Military Application Submarines

In 1912 the U.S. Navy replaced its submarine gasoline engines with safer and more efficient diesel engines. The oil-burning diesel engine required no complicated ignition, or sparking systems, and it produced fewer noxious fumes. The USS Skipjack (SS-24) and USS Sturgeon (SS-25) were the first U.S. submarines equipped with diesel propulsion.

The diesel engine and the electric battery remained the power source for submarines until nuclear power was introduced in the 1950's. While many modern submarines are still diesel powered, nuclear power has become the propulsion system of choice in US submarine construction. The British Royal Navy's submarine force is also entirely nuclear-powered. The French, Russian, and Chinese Navies use nuclear propulsion for some of their submarines.

World War I

The United States entered World War I in 1917 with a total of 24 diesel powered submarines.

U.S. Navy subs patrolled the waters off the U.S. East Coast and deployed overseas to the Azores and Ireland. The American submarines primary missions were to escort Allied shipping and counter the German U-boat threat.

Though there were no confirmed sinkings of U-boats by American submarines the number of German attacks repulsed by near misses showed the submarine to be an effective anti-submarine weapon. However, it was Germany's use of the U-boat in World War I that demonstrated the vital role the submarine would play in the next global conflict.

Naval Shipyards & All-Welded Submarines

After the war, the U.S. Navy slowly built up its sub force. Construction contracts with commercial shipyards were cut back, forcing the Lake Torpedo Boat Company to go out of business in 1922. The Portsmouth Naval Shipyard in New Hampshire became one of the largest submarine builders in the U.S. and between 1924 and 1929 the Portsmouth yard designed and built five 381-foot V-class submarines. Between 1932 and 1941, Portsmouth built an additional 22 submarines in the 1500-ton category.

It was during this period that the first all-welded submarine, USS Pike (SS-173), was completed. The welded hull allowed Pike to submerge to much greater depths than her predecessors and at the same time provided greater protection against depth-charge attacks.

Sonar

Sonar </od/sstartinventions/a/sonar_history.htm> is a system for detecting submarine sound in the water. It was first developed by the British for use against U-boats in World War I. Radar uses radio waves to detect objects on and above the land and sea surface. Radar was developed in the 1930s to detect aircraft.

The USS Holland Submarine - John Holland

The USS Holland Submarine - John Holland

In 1862, the United States Federal navy tested a prototype submarine called Alligator </od/weirdmuseums/ig/Submarine-Photo-Gallery/The-Alligator-Submarine.htm>. The Alligator submarine was intended for operations in the James River below Richmond, Virginia. However, the Alligator proved too large for diving in the river's shallow waters. The Alligator sank at sea while it was being towed to the Charleston operating area.

In 1872, the Navy unsuccessfully tested Intelligent Whale </od/weirdmuseums/ig/Submarine-Photo-Gallery/Intelligent-Whale-Submarine.htm>, another hand crank-powered submarine that failed. After the Intelligent Whale's failure as a submarine, inventors realized that until a propulsion method better than manpower could be developed for underwater use, submarines were not going to be worth the effort.

John Holland

By the last decade of the nineteenth century steam propulsion had replaced sail power in the U.S.

Navy. In 1896, the Navy insisted that submarine designer John Holland build his first contract submarine named the Plunger, with a steam engine for surface propulsion.

John Holland, an Irish-American school teacher and inventor, objected to steam power in submarines. Nonetheless John Holland built the Plunger with three steam engines to meet the Navy's prescribed surface speed.

The Plunger

During dock trials of the Plunger submarine, the temperature in the fire room reached 1370F with the power plant at 2/3 rated output. Similarly, during Plunger's sea trials a crewmember reported, "When we tried to submerge, it was so hot no one could live in her." Today, the nuclear reactor has eliminated this drawback to a heat source and submarines are driven by steam. But, before the advent of nuclear power, the internal combustion engine was the submarine's first viable source of power.

Internal Combustion Engine

The internal combustion engine </library/inventors/blinternalcombustion.htm> offered speed and comparative endurance on the surface, but its deadly carbon monoxide exhaust fumes and high oxygen consumption were obstacles to life beneath the surface. By 1900, submarine designers had solved this problem with the storage battery and electric motors. John Holland was the first to conceive of employing electric motors and the internal combustion engine to power a submarine.

John Holland and Simon Lake

John Holland and another American, Simon Lake, became the first modern submarine designers. They began their experiments in the last decades of the nineteenth century, John Holland in the 1870s and Simon Lake in the 1890s.

John Holland built six submarines, including one under government contract, before the Navy would accept one of his underwater boats. The Navy also considered, but decided not to accept, Simon Lake's Argonaut, an advanced version of his Argonaut, Jr.

Simon Lake's Argonauts had wheels with which to crawl along shallow bottoms and air locks to permit divers to enter and leave the wooden hulk while it was submerged.

USS Holland

In 1900, John Holland sold the US Navy its first viable submarine, USS Holland (SS-1) </od/weirdmuseums/ig/Submarine-Photo-Gallery/USS-Holland--SS-1-.htm>. This submarine was originally named Holland VI and was not developed under Navy contract. Holland VI was designed and built by its namesake using his own funds. USS Holland had the "amazing speed" of seven knots surfaced, made possible by her 45-horsepower internal combustion engine. She also had an endurance of several hours submerged when running on rechargeable storage batteries.

The USS Holland was armed a single torpedo tube and a pneumatic dynamite gun that fired through an opening in the bow. The Holland carried three Whitehead torpedoes, each with a pressure-sensitive piston that controlled the depth of the torpedoe run. The torpedo's stability was controlled by a pendulum, while direction was controlled by a gyroscope. A number of modern torpedoes used similar principles.

John Holland and Simon Lake were at odds in developing their submarine concepts.

John Holland and Simon Lake were at odds in developing their submarine concepts.

Simon Lake experimented with boats that ascended vertically according to negative or positive buoyancy controlled by pumps and tanks.

John Holland's boats were given neutral buoyancy by admitting water to balance the weight of the boat with the weight of water it displaced. With diving planes and a constant source of power, Johm Holland's boat could dive and surface on diagonal lines.

John Holland Submarine Diving

John Holland's principle, with some alternatives for fast diving and surfacing, is still used by modern submarines.

For all its innovations, the USS Holland </od/weirdmuseums/ig/Submarine-Photo-Gallery/USS-Holland--SS-1-.htm> had at least one major flaw; lack of vision when submerged.

The submarine had to broach the surface so the crew could look out through windows in the conning tower. Broaching deprived the Holland of one of the submarine's greatest advantages, stealth.

The Periscope

Lack of vision when submerged was eventually corrected when Simon Lake used prisms and lenses to develop the omniscope, forerunner of the periscope </library/inventors/blperiscope.htm>.

Sir Howard Grubb, designer of astronomical instruments, developed the modern periscope that was first used in Holland-designed British Royal Navy submarines. For more than 50 years, the periscope was the submarine's only visual aid until underwater television was installed aboard the nuclear powered submarine USS Nautilus </od/weirdmuseums/ig/Submarine-Photo-Gallery/USS-Nautilus.htm>.

Robert Fulton and the Nautilus Submarine

Robert Fulton and the Nautilus Submarine

Then came another American, Robert Fulton, who in 1801 successfully built and operated a submarine in France, before turning his inventing talents to the steamboat </library/inventors/blsteamship.htm>.

Robert Fulton - Nautilus Submarine 1801

Robert Fulton's cigar-shaped Nautilus submarine was driven by a hand-cranked propeller when submerged, and had a kite-like sail for surface power. The Nautilus submarine was the first submersible to have separate propulsion systems for surfaced and submerged operations. It also carried flasks of compressed air that permitted the two-man crew to remain submerged for five hours.

William Bauer - 1850

William Bauer, a German, built a submarine in Kiel in 1850, but met with little success. Bauer's first boat sank in 55 feet of water.

As his craft was sinking, he opened the flood valves to equalize the pressure inside the submarine so the escape hatch could be opened. Bauer had to convince two terrified seamen that this was the only means of escape. When the water was at chin level, the men were shot to the surface with a bubble of air that blew the hatch open. Bauer's simple technique was rediscovered years later and employed in modern submarines' escape compartments that operate on the same principle.

Horace Lawson Hunley

During the American Civil War, Confederate inventor Horace Lawson Hunley converted a steam boiler into a submarine.

This Confederate submarine called the could be propelled at four knots by a hand-driven screw. Unfortunately, the submarine sank twice during trials in Charleston, South Carolina. These accidental sinkings in Charleston harbor cost the lives of two crews. In the second accident the submarine was stranded on the bottom and Horace Lawson Hunley himself was asphyxiated with eight other crew members.

The Hunley

Subsequently, the submarine was raised and renamed the Hunley </od/weirdmuseums/ig/Submarine-Photo-Gallery/Horace-Lawson-Hunley.htm>. In 1864, armed with a 90-pound charge of powder on a long pole, the Hunley attacked and sank a new Federal steam sloop, USS Housatonic, at the entrance to Charleston Harbor.

After her successful attack on Housatonic, the Hunley disappeared and her fate remained unknown for 131 years.

In 1995 the wreck of the Hunley was located four miles off Sullivans Island, South Carolina. Even though she sank, the Hunley proved that the submarine could be a valuable weapon in time of war.

Biography - Horace Lawson Hunley 1823-1863

Horace Lawson Hunley was born in Sumner County, Tennessee, on 29 December 1823. As an adult, he served in the Louisiana State Legislature, practiced law in New Orleans and was a generally notable figure in that area.

In 1861, after the start of the American Civil War, Horace Lawson Hunley joined James R. McClintock and Baxter Watson in building the submarine Pioneer, which was scuttled in 1862 to prevent its capture. The three men later constructed two submarines at Mobile, Alabama, the second of which was named H.L. Hunley. This vessel was taken to Charleston, South Carolina, in 1863, where it was to be used to attack blockading Union ships.

During a test dive on 15 October 1863, with Horace Lawson Hunley in charge, the submarine failed to surface. All on board, including Horace Lawson Hunley, lost their lives. On 17 February 1864, after it had been raised, refurbished and given a new crew, H.L. Hunley became the first submarine to successfully attack an enemy warship when she sank USS Housatonic off Charleston.

History of the Submarine - David Bushnell 1742-1824

History of the Submarine - David Bushnell 1742-1824

From Mary Bellis </mbiopage.htm>,

David Bushnell's Turtle Submarine

The first American submarine is as old as the United States itself. David Bushnell (1742-1824), a Yale graduate, designed and built a submarine torpedo boat in 1776. The one-man vessel submerged by admitting water into the hull and surfaced by pumping it out with a hand pump. Powered by a pedal-operated propeller and armed with a keg of powder, the egg-shaped Turtle gave Revolutionary Americans high hopes for a secret weapon - a weapon that could destroy the British warships anchored in New York Harbor.

Turtle Submarine - Use as a Weapon

The Turtle's torpedo, a keg of powder, was to be attached to an enemy ship's hull and detonated by a time fuse. On the night of September 7, 1776, the Turtle, operated by an Army volunteer, Sergeant Ezra Lee, conducted an attack on the British ship HMS Eagle.

However, the boring device that was operated from inside the oak-planked Turtle failed to penetrate the target vessel's hull.

It is likely that the wooden hull was too hard to penetrate, the boring device hit a bolt or iron brace, or the operator was too exhausted to screw in the weapon. When Sergeant Lee attempted to shift the Turtle to another position beneath the hull, he lost contact with the target vessel and ultimately was forced to abandon the torpedo. Although the torpedo was never attached to the target, the clockwork timer detonated it about an hour after it was released.

The result was a spectacular explosion that ultimately forced the British to increase their vigilance and to move their ship's anchorage further out in the harbor. Royal Navy logs and reports from this period make no mention of this incident, and it is possible that the Turtle's attack may be more submarine legend than historical event.

どうやらあの人が判らないらしい。
It appears that he cannot identify that man there.

「あら ごめんなさい。どうやら間違え電話をしてしまったようだね。」
'Oh, I'm sorry. I guess I have the wrong number.'

どうやら、そのみすぼらしいアパートは空き家のようだ。

--- Comments ---
As for the first example, J should be どうやら彼_は_分からないらしい。
彼が分からないらしい would be, it seems she doesn't know who he is.
(contributor: Miki)

どうやら彼が分からないらしい means someone (who remains unidentified but
not the speaker) cannot discern him.

どうやら彼は分からないらしい means 'he' is not able to discern something
(not dicclosed) as observed by the speaker.

(contributor: bamboo4)

Accordingly, 彼が分からないらしい should be changed to 彼は知らないらしい.


(contributor: bamboo4)

Is the 'somehow' meaning similar to nantoka (なんとか)? If so, there is no
entry for that currently... (contributor: yookoso)

Yes, it seems to be so.
ex#1279, 3933 and 3934 どうやら can be replaced by なんとか.
(contributor: Miki)

#3095
I would say 'どうやら、あの人は判らないらしい。'

#3930
I would say 'どうやら、私はバスの中で財布を盗まれたようだ。'

The other examples are OK. (contributor: Nick)

#3095 どうやら、(あの人は he)あの人が(that man there)判らないらしい。
#3930 Both …らしい。 and …ようだ。 are fine. (contributor: Miki)

#3095
彼はどうやら、あの人が誰なのか見分けがつかないようだ。 (contributor: Nick)

〜らしい (I hear that... / Someone says that...)
〜ようだ (It seems that...)
These are not interchangeable. (contributor: Nick)

Grammar a Day - Level 1 - 貰う (morau)

貰う (morau) - have someone do something for you

--- Notes ---
morau is a fairly informal/plain/gruff way of asking someone to do
something for you.

書いてもらうか? = can you write it for me?
- something a boss might say to a junior

書いてくれる?
- more common, not overly polite, OK to use between friends

書いて頂けますか?
- slightly keigo, something you might say to your boss

やる is a pretty rough verb.
With 貰う makes things sound pretty blunt:
  やってもらう = hey, do it for me.

--- Examples ---
私は父にカメラを買って貰った

My father bought a camera for me

私は友達に日本語を教えて貰っている

I am having a friend teach me japanese

コンビニで、何か買って貰いたいですか?
At the store, is there anything you want me to buy for you?

4時に医者に診てもらう予約をした。
I made an appointment to see the doctor at four o'clock.

あなたはグリーン先生に英語の発音を直してもらうべきだ。
You should have Mr Green correct your English pronunciation.

今すぐ髪を切ってもらう必要はないよ。
You need not have a haircut right now.

ことによると、きみにも一緒にきてもらう。
Maybe you better come with us.

このヒーターは故障しているようなので、彼に修理してもらう予定だ。
Since this heater seems to be out of order, I'll have him repair it.

この椅子を修理してもらうのにどれくらいかかるのでしょうか。
What would it cost to have this chair repaired?

この仕事は誰にもしてもらうわけにはいかない。
I can't get this work done by anybody.

この車は修理してもらう必要がある。
This car needs repairing.

じゃあ、言わせてもらうけど。
Let me tell you something.

--- Comments ---
貰う and あげる are two faces of one coin. The former describes the
situation from the position of a receiver, whereas the latter describes the
situation from the side of the giver. Note also that やる, also the verb
describing the situaiton from the standpoint of the giver, is relatively
impolite as contrasted to あげる. When you feed a pet you use やる but that
can also be used in case of humans if the receiver is inferior to you.In
the same vein, 貰う and くれる have the same kind of semantic difference as
would exist between あげる and やる.
(contributor: bamboo4)

bamboo - tried to distill your comments into a note at the top. feel free
to add notes instead of comments when you think you have a summary
explanation... (contributor: dc)

where does fit on this continuum? I have heard it used mainly for
'receiving'.
are & kind of opposites like & ? ie the polite forms of give and
receive/ also used as 'do for you' & 'you do for me' (contributor: dc)

'itadaku' ia a honorific of 'morau.' 'itashimasu' does not belong here.
(contributor: bamboo4)

bamboo4- if you put the items like itadaku in square brackets, rather than
'quotes' they will come up as hilited links like this:
btw can you explain ? (contributor: dc)

is 'to do' spoken in a modest manner, or which the Japanese call 謙譲語.
私がいたします would be directed to your superior meaning that 'I will do
that.' It has nothing to do with 'giving' or 'receiving' which would be
involved in 貰う and あげる.
(contributor: bamboo4)

Another honorific for give is {さしあげる}that can be used in such cases
as {してさしあげる}meaning as a very polite expression. It can be used
with a number of other verbs, too. (contributor: bamboo4)

Hi, I think that 'morau' is actually not a Level 1 JLPT expression. This
is perhaps more like Level 3 expression, since this is normally not
considered an advanced expression.

I also think that in practice, Shite Sashiageru is not really used often.
Rather, they would use 'shitai to omoimasu' as a replacement. I think the
only situations in which you would use Shite Sashiageru is to someone who's
of higher social ranking than you, and also very close to you. (Perhaps
your close grandmother, or someone like that) (contributor: nhk9)

Gold Market

Gold Market

For the week, spot gold closed at $731.5, up $23.9 or 3.38 percent. Gold equities, as measured by the XAU Gold Index (10), rose 8.58 percent for the week. The U.S. Trade-Weighted Dollar Index (11) slid 1.28 percent for the week.

Strength

  • The Federal Reserve Bank's 50 basis point rate-cut pushed gold to a 28-year high this week as the inflationary effects of a falling dollar fuel investment demand for gold.
  • Gold stocks assumed a leadership position in the market this week, outpacing the S&P 500 by 578 basis points.
  • Gold has also attracted attention globally. Gold oriented ETFs have returned 5.2 percent in the last month versus 4.4 percent for India's Sensex stock exchange.

Weakness

  • Despite recent strength in gold equities, junior gold stocks have lagged the performance of large capitalization gold companies over the past 60 days.
  • According to Standard Bank Asia Ltd., the hoarding of physical gold in Asia is creating a discount to spot gold in countries like China.

Opportunity

  • According to Goldman Sachs, the U.S. dollar could depreciate by another 2-3 percent against Asian currencies in the next 3-6 months.
  • Silver bullion may outperform gold bullion prices in the upcoming weeks as silver has lagged over the last three months.

Threat

  • Given the rapid decline in the U.S. dollar central banks may step in begin buying dollars in attempt to stabilize the currency.
  • Suresh Hundia, president of the Bombay Bullion Association, stated recently that both the demand for gold jewelry and gold investments will "dry up" at these high price levels.
