Highest Scoring Entry for 2007 Physics World Quiz Contest?

[ZapperZ]

Hey, Physics World has http://images.iop.org/dl/physicsweb/PWDec07quiz.pdf" from 2007. There's a £50 prize for someone who gets most of the answer.

Wouldn't it be nice if a PF member wins this? :)

Zz.

I've got the answer for "B" at the top of the page concerning this sign:

http://www.iaea.org/NewsCenter/images/newradiationsymbol_300x200.gif


The image in the top portion of the triangle is a fan blade----these signs are in public bathrooms. So the sign indicates, if the fan isn't working---it's best to leave at a fast pace!

B.
The symbol is intended for IAEA Category 1, 2 and 3 sources defined as dangerous sources capable of death or serious injury, including food irradiators, teletherapy machines for cancer treatment and industrial radiography units. The symbol is to be placed on the device housing the source, as a warning not to dismantle the device or to get any closer. It will not be visible under normal use, only if someone attempts to disassemble the device. The symbol will not be located on building access doors, transportation packages or containers.

One thing's for sure, it ain't the entrance to the Trilateral Commision.

During a a high-pressure test of critical components:
"At 20 bar, there was a sudden release of helium gas (used to cool the magnets), something went bang, and sirens sounded, alerting the fire brigade."

So Jimmy, are you going to enter this contest or what? :)

Zz.

 

[Kurdt]

I think if anyone enters from this thread then the money should go to PF.

 

[Jimmy Snyder]

So Jimmy, are you going to enter this contest or what? :)
Zz.

I might if I get all of them. I assume there are many people who can google as well as or better than I.

Korolev?

I'm not sure about this one. My guy spent only 6 years in prison and only a part of that in a labor camp. It was before, not after sputnik.

Inside were two one-watt radio transmitters and three silver-zinc batteries - two for powering the radio beacons and one for a ventilation fan. The sphere was filled with nitrogen gas pressurised to 130 kilopascals (1.3 atmospheres).

This article mentions some of the equipment, but I don't know if it is an exhaustive list.

20. I can't find this one. Here's an article that suggests that there was no such person.

Perhaps he was the janitor and kept the keys. Anybody got a better answer?

It seems I have found all except for 12 and 20. George Jones has the answer to 12. If someone gets 20, then we should follow Kurdt's suggestion and send the lot in as physicsforums.

 

[Kurdt]

Oswald Putze might be the answer to 20. I tried googling his name and he was certainly involved but there's not much info on him. I thought he'd at least have a wiki article if he was the one.
