Cool Science thread

Pretty cool. Did you notice this house?

Got front elevations on your mind Ice? Problems could always be worse, eh.

[iceman]

Yeah that right there is a real problem.

That EM drive is just fucking awesome.

^^^Oh, I want one. Awesome when he played the music into it.

There must a be a limit to the amount of data that can be transferred between two points in a given time. I wonder what that is and how far this test is from that amount.

There is indeed a theoretical limit determined by the Shannon-Hartley theorem.

C = B log2(1+S/N)

C is the channel capacity in bits per second;
B is the bandwidth of the channel in hertz (passband bandwidth in case of a modulated signal);
S is the average received signal power over the bandwidth (in case of a modulated signal, often denoted C, i.e. modulated carrier), measured in watts (or volts squared);
N is the average noise or interference power over the bandwidth, measured in watts (or volts squared); and
S/N is the signal-to-noise ratio (SNR) or the carrier-to-noise ratio (CNR) of the communication signal to the Gaussian noise interference expressed as a linear power ratio (not as logarithmic decibels).

So theoretically really comes down to how much bandwidth (simple explanation freq bands) and how much power they are putting into the signal. Introducing amplified noise doesn't help so the electronics have to be designed for low noise up front.

Heh, no, I didn't see that. Looks like a gorgeous house with an unbelievable view! But... I see it ending up like the ship in it's back yard not too far off from now.

This thread is like diving down the rabbit hole. My stomach had to remind me that time was not relativistically slow in the science thread.

Great read for those into geology:

...giving spiders water that is infused with carbon nanotubes makes them weave silk stronger than any known fiber.

Think of the possibilities for Shit Knives!!!!!

From the comment...

This really is super cool, just one little concern. It has to do with the study quote "This leads to mechanical hardening of teeth, jaws, mandibles, ovipositors and to an enhancement of silk toughness." Now this would produce some seriously kick ass spiders and knowing our previous stellar history in containing dangerous things (especially when there is big money involved) this could get very interesting very fast.

How long until one of these nano enhanced spiders bites Peter Parker?

.... just as long as it takes to irradiate the little fuckers. Speaking of little, I vote for splicing in some extinct mastodon DNA to really get this party goin'. If not available, I'd settle for some Honey Badger DNA.

Not sure that this falls under the purview of "science" or that it's necesscelery cool, but it seems the Chinks are trying to outdo the Japs when it comes (cums?) to self-pleasuring technologies.

That EM drive is just fucking awesome.

Wasnt there some guesstimation that the X-37B was carrying a EM drive in its payload for the next mission?

Not sure how I'll react when these start showing up in the gym, next to the elliptical trainers .......

T-Cells does a body good:

The video description on youtube gives a bit of an explanation. And with the shitty TGR video tags, you have to go there to view full screen anyway.

SDO is the shit, pre SDO and SOHO we knew a laughable amount about the sun which is only by far the most important body in our solar system.

817mil and we've learned so much about the sun's magnetic field and it's interactions with other fields including earth.

Neil deGrasse Tyson was good on Charlie Rose last night. Not posted yet but look for it.

I should have DVR'd it. I started falling asleep around midnight and missed a couple parts.

As insanely cool as that video is to watch, the amount that has been learned from these projects is even cooler (for something that is so hot ).

Wow, Lexus.

Cool as fuck, but that's no ordinary skate park. There are permanent electromagnets in the ground.

[BmillsSkier]

Yup. Article mentions that but didn't showcase the making of it.

Really cool!
