Some one claimed that physicists where claiming a connection with metaphysics. Is there any truth in that whatsoever? If so, how would they relate?

enough to be very accurate enough and better than deduction. I find, for instance, if I know I'm going to California tomorrow, that gives me a big enough picture to answer large questions like should I by a house here tomorrow and small decisions, like, I will need a toothbrush. What I mean is are we putting too much emphasis on deduction and missing the world view, considering that atoms aren't having a problem, people are. And shouldn't induction be used more in science instead of getting more and more isolated from the real world and other disciplines.

i had to make log(5)17 a common log with a base of 10..

so ...i made it 10^(log(5)17) which is log X = log (5)17 which is log X = 1.760. is that the same thing as making hte equation a common log??

What does this mean analytically and what can we deduce from that information.
Can sound pressure level deduced from that .If not what do we have to do to get that done.

A reading was taken with the temperature on an antenna I was testing, the temperature gun uses an InfraRed thermometer. I would get temperatures in upwards of 280 degrees farenheight while transmiting, and temperatures of around 110 degrees farenheight while not transmitting (wich was normal). Does anyone have a theory for why this would happen?

I can watch the temp rise as soon as the sun goes down. After it gets cooler outside (under 72) I open some windows (one with a fan in it) on opposite sides/ends of the house and make sure the outflow is slightly larger than the inflow so I don't create a backpressure situation. It can be 60 outside and even with the fan on all night I still can't get the house under 70 degrees.

The house faces the West so I know it is getting baked.

Any options to cool it faster? I have a big fan and use it on high. Why does it get hotter once the sun gets off it?

I walk out of the room back where seconds later on i hear the fight, where again seconds later on they both entered the room and asked me how did i know they will fight? and was i eves droping on them in the past , i just told them the truth, they looked at me as if i was lying but i cried and told them i saw it happening, i even told mom of her conversation about my dad, which suddenly to her amzing it was her thoughts about my dad at this moment before she started the fight but she denied that she has spoken it loud it was her thoughts.. any how that is all and some how i do believe that something happened doesnt makes me an alien but some scientific explanation did occure and i need explanation?

my theories are:

the primary elements that they evolved from differ from ours (carbon-based).

this could also apply to differing temperatures on their home planet.

or

their planet came into existence a few billion years before ours, giving them much more time to evolve, as well as develop the ability for space travel.


what do you think?
