Every measuring instrument/device have percentage errors. And due to these percentage errors we can never consider any measurement to be a perfect whole number.

Eg: If we manage to measure out 1.0g of matter, we still can't say that it can't be 1.01g(which would no longer make it a whole number.).

So the question is, are whole numbers possible?

Eg: N2(colourless gas)+O2(colourless gas)=NO2(brown coloured gas)

I've worked out mine because I'm applying to Uni, and I've shoved it into my personal statement. I want to make sure I have a reasonable (approximate) answer, so if you fancy working out an approximation of your angular momentum, it would be really useful. 

It's also quite a fun experiment. Don't get too dizzy. 

Hypothetically, if a child was brought up without any reference to our human measurements of time (seconds, minutes, hours, days etc.), would it affect his/her concept of time passing?

For instance, we all have a general idea of how long 30 minutes is, but if someone was brought up without the ability to estimate how many minutes have passed, would they percieve time differently to the rest of us?

On various TV programs about the above phenomena, I've heard people say that the former is flying insects and the latter dust but has anybody ever carried out experiments to prove this, one way or the other? (Hit dusty furniture and film it or release a heap of flying insects and video the result).

Is it possible to re-experience a physical experience ,purely out of memory,for e.g,can you contemplate and in a way literally experience the feeling you get, say,when you take a walk in winters?Surely,the brain must store such things?
