The photo electric effect tells me that light is a particle and electrons are dislodged by direct collisions between photons and electrons.

However, why is it that thermionic electrons can be build up by gradual accumulation of energy?

Find the nth term of the following sequence:
1, 2, 4, 7, 11, 16, 22, 29..
I know that the differences are 1, 2, 3, 4, 5, 6, 7 and the differences of differences are 1 but I can't seem to find the nth term!

Or scientists who argue although there is slight warming, the causes are unknown and the likely future effects unknown or beneficial.

According to CNN (I searched using the terms "asteroid", "impact", Earth", "2028") an asteroid has been seen approaching earth. It will pass on October 26th. 2028: the best estimate is that it will miss by 30,000 miles, but as the error term in the estimate is up to 180,000 miles it could hit. The explosion would be equivalent to 2 million Hiroshima bombs.

Does anybody know anything about this? E.g what time would it hit,which side of Earth is in line, whether it would hit sea (with the implications of huge waves) or land, and what the effects would be?

Also, what are the politicians and scientists doing to divert this object if necessary? It obviously ranks at least alongside problems such as global warming and terrorism.

Are they pretty heavy? I've hear that most of them are. Do you have to pretty much get on your knees to look through it?

That idiot Steve Irwin - the australian nature lover who fed an aliigator while holding his 2 month old infant - has finally been killed by Nature.

A Manta Ray whipped him with its tail while he was swimming -scuba diving near a coral reef.

How exactly does a manta ray kill you? Does it put a huge hole in you or is the poison just very strong?

Is there a body suit that can protect you from a ray's tail?
