1) It's nowhere near 40%, much lower.
2) The holes are too small to flow any appreciable amount of air, even though there are many of them.
Also, fluid dynamics would dictate that those holes would become effectively blocked by turbulence when in anything more than a light breeze2) The holes are too small to flow any appreciable amount of air, even though there are many of them.

"You know that the copper in the Plastocyanin family of copper-binding proteins comes from a star going supernova" just doesn't have the same ring to it (excuse the pun)

Russian cosmonauts used to pack a shotgun in case they landed in Siberia and had to fend off bears.
i'm not doubting you, but surely a large calibre handgun would be a better combination of space/weight/stopping power/simplicity and amount of ammo (6 shooter .45 ftw...)Greg_D said:

Shotgun does not weigh much more and requires far less finesse.eybic said:
It was indeed a pistol
Kind of, it used two smoothbore barrels loaded with 28 gauge shot and one rifled barrel underneath with a rifle calibre round. So it was really a sawn off shotgun and rifle.Edited by captain_cynic on Thursday 14th June 13:10

they really do weigh a lot more, i'm a reasonably experienced shot and know the relative weights of most types of firearm. A pump action shotgun with 6 cartridges loaded will weigh probably treble a similarly equipped pistol, and will take up probably 5x the space. if an astronaut can't be trained to fire a pistol vaguely straight into the centre of mass of a bear, they probably shouldn't even be on the mission....
Erm... the pistol with two shotgun shells linked to above is 2.4 KG with stock, a .50 desert eagle is 1.8 KG. Not really going to make much of a difference.I'm calling b
ks on you being an actual shooter if you think a small shotgun is 5 times as big as a large calibre pistol. A sawn off pump action will easily be under 3KG and maybe occupy twice the space, less if it has a folding stock... However a combination gun was made. It was a breech loader because if you cant neutralise the bear with one or two shots, you were bear food. Also, pilots were not chosen for their marksmanship and you can put a .45 round into a bear and it will keep charging unless you hit something vital. The time saved by not having to aim accurately was the difference between life and death. Bears are big creatures.

I personally would be rather doubtful of the effectiveness of any shotgun round against a bear, let alone the (rather small) 28 bore in the TP-82.

a 28 gauge shotgun shell is little more than a child's toy, they're no thicker than your little finger - they're certainly not going to stop a charging bear.
the .45acp 1911 (would not be chosen by the russians because it is an american gun ,but they would almost certainly have something similar in their armoury) is a little over 1kg empty. if they provided hollowpoint or polymer tipped ammo, it'd certainly give a bear a lot more to think about than a 28ga shell..... and you have 7 times to get it right before slotting in another clip.

Only on PH can you randomly dip into a topic and read a debate about Russian Cosmanauts killing bears (or not)
Brilliant! I've got a topic to talk to my pal about next time we go for a beer.
Did NASA Astronauts in the Apollo missions carry any kit in the event of them not being recovered on time? Fishing lines perhaps?
Its a genuine question.

Its a genuine question.
There are 80,658,175,170,943,878,571,660,636,856,403,766,975,289,505,440,883,277,824,000,000,000,000 different possible permutations for a a shuffled deck of cards (52!). To shuffle every possible permutation, assuming that you can shuffle a different permutation every second...
Start by picking your favorite spot on the equator. You're going to walk around the world along the equator, but take a very leisurely pace of one step every billion years. The equatorial circumference of the Earth is 40,075,017 meters. Make sure to pack a deck of playing cards, so you can get in a few trillion hands of solitaire between steps.
After you complete your round the world trip, remove one drop of water from the Pacific Ocean. Now do the same thing again: walk around the world at one billion years per step, removing one drop of water from the Pacific Ocean each time you circle the globe. The Pacific Ocean contains 707.6 million cubic kilometers of water. Continue until the ocean is empty. When it is, take one sheet of paper and place it flat on the ground. Now, fill the ocean back up and start the entire process all over again, adding a sheet of paper to the stack each time you’ve emptied the ocean.
Do this until the stack of paper reaches from the Earth to the Sun. Take a glance at the timer, you will see that the three left-most digits haven’t even changed. You still have 8.063e67 more seconds to go. 1 Astronomical Unit, the distance from the Earth to the Sun, is defined as 149,597,870.691 kilometers. So, take the stack of papers down and do it all over again. One thousand times more. Unfortunately, that still won’t do it. There are still more than 5.385e67 seconds remaining. You’re just about a third of the way done.
To pass the remaining time, start shuffling your deck of cards. Every billion years deal yourself a 5-card poker hand. Each time you get a royal flush, buy yourself a lottery ticket. A royal flush occurs in one out of every 649,740 hands. If that ticket wins the jackpot, throw a grain of sand into the Grand Canyon. Keep going and when you’ve filled up the canyon with sand, remove one ounce of rock from Mt. Everest. Now empty the canyon and start all over again. When you’ve levelled Mt. Everest, look at the timer, you still have 5.364e67 seconds remaining. Mt. Everest weighs about 357 trillion pounds. You barely made a dent. If you were to repeat this 255 times, you would still be looking at 3.024e64 seconds. The timer would finally reach zero sometime during your 256th attempt.
(god I love that)

The average depth of a UK canal is only 3 to 4 feet.
Weirdly, even though I know that canals are quite shallow, when I walked across Pontcysyllte Aqueduct and had to deal with oncoming people on the towpath, I was far more worried about falling in the canal (I can't swim) than off the side of the aqueduct.Fun piece of historical engineering to go and witness but that element of it (or my overactive imagination) made my blood run cold.
Related... The Falkirk wheel can complete a revolution using no more electricity than is required to boil a kettle, and further related to the weight impact upon an aquaduct of a heavy boat, the weight in each trough remains the same whether there is a boat within or not.
I've been around that wheel in one of their tourist boats. Great to have experienced but it's better to watch from outside.
