MUST KILL HAWKING MUST KILL HAWKING MUST KILL HAWKING MUST KILL HAWKING ps. The Feynman Lectures on Physics.

Opera. Opera. Opera.

Getting a control/test subjects is pretty easy. You just have to sit down and think 'What am I going to measure?' For instance, if I was measuring the effect certain chemicals had in the water of plants as to respiration, then my control would be identical (plant in water) without the things you're testing (the added chemicals).

I just want to play that Hawking game

ZERG RUUUUUUUUUSH!

It's the red giant phase he's talking about. ps. Faf: you can ignore the first 850 of those 1000 years. Horse driven carts to, say, (in the near future), maglev trains, and nothing to flight... Although personally I'd go back 350 years, to Newton.

Oh, and a control should be, say, a brick or something rather than just nothing. Something that shares all the properties of the things you're testing apart from the variable. Paper, or similar.

Saying 'live plant' and 'dead plant' as seperate things is about as useful as saying 'food'; I'd presume that 'different types of plants' was the condition undergoing testing.

Seperate your paragraphs, it makes it much easier to read

If it's acting on the same point, otherwise you'll get moments and stress.

a = :sum:F/m (effectively)

Acceleration is the result of, well, a resultant force. You can't just split it down.

What?

Acceleration is a result of the NET RESULTANT FORCE.

WHAT DEFINITION OF ACCELERATION ARE YOU USING? It appears different from everyone else's, :lcdelta:v/:lcdelta:t

It's not accelerating. THERE IS NO RESULTANT FORCE. (also, you can't have a force equal to a mass)

it's not accelerating at the moment, because there's no resulting force. On an object in mid air, there is a resulting force (gravity) so there's an acceleration. (F=ma) The desk is providing a normal reaction to your phone, so there's no force.

I said that one above

???????

No. Time exists as a mathematical dimension. See: GR.

An additional argument: If someone isn't accelerating when it's stationary, how would anything EVER move? ps :lint:0dt can still equal a constant, for the maths.

It is still accellerating. At the peak of its trajectory, the velocity is instantaneously 0. IMI: Why would gravity stop when its at the peak?
