Science Talk

[mawk]

no I mean that it's on youtube in the first place

 

[Sgt. Cookie]

No its just quicker than waiting for the bbc to release it on DVD. Its only a theory is a bbc 4 show.

 

[Ellie]

Youtube's just a mode of releasing things dude, the community may be shite but that doesn't immediately debunk everything shown on it.

 

[Twirly]

Don't have time to explain now just wanted to say that. :box:

HEH
GET IT

 

[Ellie]

Anyone been watching the series on I think it's channel 4 this week? It's been pretty cool. Voiceovers from Hawking and Dawkins and various other rhyming names I'm sure.

 

[Daxis]

nope, no cable, and don't particularly care for it. Internet has everything.

And NOVA IS AWESOME. Einstein's big idea was epic.

 

[Ellie]

I should start reading more science books again. I've started understanding them a lot more now.

 

[Cryranos]

My science teacher said that they're still proving Einstein's theories correct.

E = mc^2 is used in nuclear chemistry to calculate mass defect.

If you know the energy produced by a reaction, you can divide it by c^2 and you get the mass defect!

I always thought that was pretty cool.

 

[Ellie]

Yeah Einstein's theory of relativity greatly goes against quantum theory. They're trying to find a quantum theory that fits relativity but in reality both are just theories - by definition a theory is not certain.

if you want to have your mind blown then look no further! :toot:

it's kind of long (~1 hour) but it's really quite incredible. there's a lot of anti-religion quips though.

 

[Ellie]

I am reading a very interesting book called "Bad Science" and recommend it to everyone.

It explains things such as dodgy cosmetics companies' claims and shit and basically calls out people like Jillian Mckeath.

Pi is exactly 3.

 

[dadevvtsvre]

Pi is exactly 3.

uhh no it's not? :/

also the other day i found out that 0.999... (continuing onwards to infinity) is the exact same number as 1. there are multiple reasons but here is more concrete mathematical proof.

0.666... = 6/9
0.121212... = 12/99
0.487487487... = 487/999
etc.

in these cases, the number of digits in the repeating number, divided by an equal number of digits being 9, will repeat the number to infinity. so how do we get 0.999...?

0.999... = 9/9 = 1

FASCINATING

more than 99% of the universe's mass comes from nothing. empty space.

if you take empty space - no protons, neutrons, electrons, photons, neutrinos, waves, etc., just empty space - it would actually have mass. somehow, quantum fluctuations give nothing mass. this means that most of the mass in our bodies comes from the empty space in between atoms, not from neutrons and protons.

this could also mean that something can come from nothing, and voila, the big bang theory is validated! yaaay physics

 

[Cryranos]

i like that proof

 

[LaDestitute]

It's commonly theorized that reptiles and mammals...when it comes to evolution, came from the same species or genus of clasfication.

FASCINATING

0.999... = 0.999...

10x 0.999... = 9.999...

9x 0.999... = 10x - 1x
9x 0.999... = 9.999... - 0.999... = 9

9x 0.999... = 9

9x 1 = 9

Therefore, 1 = 0.999...

Can we please have a religion talk thread? I feel we are biased.

 

[Ellie]

Religion and Science are not mutually exclusive and have nothing to do with one another. You're free to make one though.

 

[Ancient Garden]

I did but it was locked on several occassions.
