Neat stuff: apparently they've theorized a bunch of these super-heavy elements, they just haven't been observed yet (until now)!
I completely agree. I think we need to consider an alien species that is advanced as we are, and what their mathematics would look like...
I think it's obvious that there would be similarities. Any similarities would probably be due to the ubiquitous nature of mathematics and hence lend credence to the 'discovery' mantra. But as far as I can see, concepts such as matrices, vector spaces and the like are merely tools we've developed and are therefore invented. An alien species would in no way need to have a theory of matrices. It's a tool mathematicians have invented to make their work a hell of a lot easier.
There are clearly both concepts discovered and invented. A prime number is not something someone has invented. Their distribution is not something someone has invented - both are discovered. How we compute them, on the other hand, is definitely invented.
I agree with you, but I think 2) would be rare. I would imagine a third would involve explorers cataloging the various species in the universe. I'm sure they would know mostly everything there is to know about physics, but would still lack knowledge of how cultures, religions, and morality develop. I would hope that any alien species would be the curious type, exploring the universe to expand their knowledge, and free of lawyers, CEOs and politicians to hinder their progress. On that note, I would bet the alien species that can stand the test of time are free of these three parasites of society.
It's not that eating meat is wrong, we're clearly designed to consume flesh - teeth (incisors), eyes (predator) and digestive system all suggest we are at least meant to consume meat. Anyone who says otherwise has a moral axe to grind based on absolute bullshit. However, what I think a lot of vegetarians (myself included) and vegans argue is that the methods we extract meat for consumption is unethical and bad for ourselves and the environment. Meat is not murder, but the way we obtain is downright awful.
No one should assume Evolution is true. They should consider the evidence, and then make a decision. That's the very reason why ID holds no weight because it puts forth no evidence. Saying something is too complex for YOU to understand is not evidence. Having belief in God as a creator is not evidence. A 4000 year old storybook is not evidence.
The point is, the same scientific method that has shown time and time again that evolution is a fact, is the very same method scientists have used to develop every other technological device and process we used today. But why is evolution challenged? Because it's one of the only scientific theories that directly challenge that dusty old text.
Multi-core gives you absolutely nothing for web-surfing, web-developement, office related stuff and anything else the majority of people use their computers for.
When game programmers catch up and generate scalable game engines that take advantage of all N cores, we'll see the majority of users benefit.
Right now, there is a small niche of users that are shitting themselves happy with the multi-core concept. Any scientific or engineering professional is absolutely in love with multi-core platforms. I started my grad studies with a single core, and was satisfied. 6 months in I switched to a dual-core platform, and I was smitten. I'm now running two PCs with Quad-cores, and I'm able to run 8 simulations at the same time, or split a single simulation into 8 parts and combine afterwards. I'm EE, so I don't code explicitly for parallel processing but I'm sure SE and CS grads can attest to my claims and exclaim even louder. Believe me, if someone offered me an 8-core, 16-core, 32-core, you name it, I would take advantage of it.

NXP RFID Cracked

· Score: 1
Depends. I'm not up to speed of the newer RFID stuff, but at the frequencies that I've seen, there is no chance you can get ANY gain out of an antenna in the kHz or 1 MHz range. Everything looks like a Hertzian dipole at those frequencies, i.e. omnidirectional or less than 2 dBi of gain. However, operate around 1 GHz or above and you could easily build handheld directive (high gain) antennas.
MIMO works independently of frequency, provided you have uncorrelated antennas. At 700 MHz, the antenna spacing on a mobile (in terms of electrical length) is so close you can't design low correlation antennas. So provided your set of antennas can scale, MIMO works at any frequency. Unless people are willing to use much larger phones, 700 MHz (or 900 MHz) will not provide MIMO communications.
That being said, designing MIMO antennas on a mobile (or any similarly sized object) at 2.4 - 2.5 GHz is quite easy.
If the mobile isn't running multiple antennas but the basestation is, you don't have MIMO, you have SIMO/MISO depending on your POV. What's your point?
It sounds very likely. Higher frequencies allow for MIMO communications, which is the next step in comm. standards. You can't pull off MIMO in the 700 MHz spectrum, so perhaps Google is on the ball for this one.
If there are any physicists out there, can they explain how we know the universe is predominantly matter? What's to say that the andromeda galaxy isn't 100% anti matter (i.e. all positrons and neg-protons.. negtons?). Is anti-matter unstable, even in a regular matter free environment? Or is there some other mechanism that shows the galaxies we observe are mostly matter?
Google was lucky to have not bought into the spectrum.
Antenna design scales linearly with frequency. Lower frequencies invariably require larger antennas. There are some ways you can get around this, i.e. accept low efficiencies, or narrow bandwidth, etc. Either way, you DO NOT want to lower your center frequency.
Secondly, and most importantly, the next gen for wireless communications will involve MIMO. I assure you, from practical experience and graduate research, you will not see multiple antennas in the 700 MHz spectrum. Nor will you see it at the 900 MHz spectrum. You might be able to pull it off at 1800 MHz, but you'll get at most two antennas. One needs to move into the 2.5 GHz and above to make a reasonably sized handheld WITH multiple antennas. You can't just place the antennas any which way and expect MIMO to work. The antennas need to have low coupling between them, so you need significant electrical distances between them. It's EASY to design multiple antennas for different frequencies (i.e. Quadband), but VERY difficult to design multiple uncoupled antennas at the SAME frequency (i.e. MIMO).
Canada has a terrific history of human rights reform, health care reform and engineering excellence. The problem with Canada (I am one, eh?) is selling out to American politics and businesses. To name a few:
- Canada should be charging the US with a slew of war-crime related offenses over Khadr.
- We should bitch-slap your current administration over Maher Arar, who by the way, is an amazing person who I speak to daily (he's in the research lab next to mine).
- We should be blocking purchases of Canadian companies by some 'US and A' companies that are the true scum of the Earth. (i.e. RADARSAT sold to ATK). Additionally, we sold THE oldest company in the world (HBC) to an American asshole.
Some parts of Canada seem ready to become America Jr. (i.e. Alberta and Toronto) but where I'm from (Ottawa) there's a strong dislike for Americanism and American politics in general. I love Americans, I just hate your politicians and business leaders.

I call BS. (I'm an EE doing my doctorate)
Your argument is the same one people in the 50s made when transistors began replacing tubes. I'm sure similar paranoia occurred when combustion replaced steam, light bulbs replaced candles (ha!).
It doesn't kill the hobbyist, it creates different ones. I was lucky enough to be on the tail end of analog and the budding beginnings of home brew digital (with uC's). Purely digital folks are not somehow disadvantaged... it's just a different take of engineering and hobbies. There's no harm with "out with the old, in the new" in this case, because the new is just as exciting and open to hobby projects as the old. In fact, one might say there are less cases of lead poisoning with the advent of uC's (haha). Furthermore, one can do a hell of a lot more with a 200-300 dollar FPGA kit than anything an analog hobbyist could dream of. Besides, these kits have D/A's on them anyway, and it's nothing to add a mixer.
In some cases you can watch people fuck, but you can't say fuck. Others you can see someone get fucked up, but can't say fuck. I mean seriously, what the fuck?
