Former HP CEO Carly Fiorina Considering US Presidential Run

The Republican nut jobs are a very small portion.

Yeah, but they're the noisiest portion.

Number of Coders In Congress To Triple (From One To Three)

grouchomarxist Re:Coding, maybe. Science for sure. (162 comments)

I agree with you that science would be better than just being a coder, but I think coding could help if it contributes to a person's ability to think logically and consistently.

Tim Cook: "I'm Proud To Be Gay"

grouchomarxist Re:Gay? (764 comments)

President Obama identifies himself as a black man. I can't find the exact quote, but he once described himself as "a black man of mixed background". Another time he said “If I’m outside your building trying to catch a cab, they’re not saying, ‘Oh, there’s a mixed-race guy.’” The point is part of the reason he probably identifies as black is because that is how other people see him. Most people think in terms of simple race categories. (I myself am of mixed-race and I know it is a pain to have to explain this, often multiple times to the same people.)

Tim Cook: "I'm Proud To Be Gay"

grouchomarxist Re:Being Gay is still technically "abnormal" (764 comments)

If you look up the definition of abnormal in a dictionary, such as this one or this one. You get definitions like: ": different from what is normal or average : unusual especially in a way that causes problems" or "Not typical, usual, or regular; not normal; deviant. odd in behaviour or appearance; strange". So even if the word has a sense as you indicate, other senses of the word are pejorative.

Oldest Human Genome Reveals When Our Ancestors Mixed With Neanderthals

grouchomarxist Re:Title seems a bit racist (128 comments)

I was wondering when the ugly racist interpretation was going to raise its head. So, far a long time Neanderthals were thought of as more primitive than humans, but now that it is known that most Europeans have Neanderthal DNA (and most Africans don't), they are being re-interpreted as being the origin of the master race.

Maybe not...

The problem with any source of energy is that it can be weaponized.

The grandparent is wrong about all three. They are probably facetiously referring to the American military bases located in these countries.

Co-Founder of PayPal Peter Thiel: Society Is Hostile To Science and Technology

grouchomarxist Re: Peter Thiel is on a book tour or something... (238 comments)

I don't think a publicist would help unless they could get Thiel to change his behavior. The fact is that Musk is getting stuff done while Thiel seems to mostly complain about other people not getting stuff done.

2014 Nobel Prize In Physics Awarded To the Inventors of the Blue LED

grouchomarxist Re:Misleading title, probable Western propaganda (243 comments)

I looked around a bit and I found no evidence that Alferov did work in this particular area. In particular, Akasaki, Amano and Nakamura worked on Gallium Nitride research, which Alferov doesn't appear to be involved with. Alferov did do research that is foundational in solid state physics. Alferov also won a Nobel Prize in Physics, so I don't think there is any effort to suppress his contributions.

2014 Nobel Prize In Physics Awarded To the Inventors of the Blue LED

grouchomarxist Re:Inventors of the first commercially worthwhile (243 comments)

Can you point to a place where the Nobel site is incorrect? Note that the Prize is for "efficient blue light-emitting diodes", not the first. Also if you look at this document is specifies that the work was in efficient blue LEDs and mentions earlier work on blue LEDs.

2014 Nobel Prize in Physics awarded to the inventors of the blue LED

grouchomarxist grouchomarxist writes  |  about 1 month ago

grouchomarxist (127479) writes "The 2014 Nobel Prize in Physics has been awarded to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura, the inventors of the blue LED.

When Isamu Akasaki, Hiroshi Amano and Shuji Nakamura produced bright blue light beams from their semi-conductors in the early 1990s, they triggered a funda-mental transformation of lighting technology. Red and green diodes had been around for a long time but without blue light, white lamps could not be created. Despite considerable efforts, both in the scientific community and in industry, the blue LED had remained a challenge for three decades.

They succeeded where everyone else had failed. Akasaki worked together with Amano at the University of Nagoya, while Nakamura was employed at Nichia Chemicals, a small company in Tokushima. Their inventions were revolutionary. Incandescent light bulbs lit the 20th century; the 21st century will be lit by LED lamps.

White LED lamps emit a bright white light, are long-lasting and energy-efficient. They are constantly improved, getting more efficient with higher luminous flux (measured in lumen) per unit electrical input power (measured in watt). The most recent record is just over 300 lm/W, which can be compared to 16 for regular light bulbs and close to 70 for fluorescent lamps. As about one fourth of world electricity consumption is used for lighting purposes, the LEDs contribute to saving the Earth’s resources. Materials consumption is also diminished as LEDs last up to 100,000 hours, compared to 1,000 for incandescent bulbs and 10,000 hours for fluorescent lights.

The LED lamp holds great promise for increasing the quality of life for over 1.5 billion people around the world who lack access to electricity grids: due to low power requirements it can be powered by cheap local solar power.

The invention of the blue LED is just twenty years old, but it has already contributed to create white light in an entirely new manner to the benefit of us all.

Shuji Nakamura went on to develop the white LED and the blue laser which is used in Blu-Ray devices."

Physicists claim detection of dark matter

grouchomarxist grouchomarxist writes  |  more than 2 years ago

grouchomarxist (127479) writes "Physicists at the University of Michigan claim that they have made the first detection of dark matter. 'Dark matter, whose composition is still a mystery, doesn't emit or absorb light, so astronomers can't see it directly with telescopes. They deduce that it exists based on how its gravity affects visible matter. Scientists estimate that dark matter makes up more than 80 percent of the universe. To "see" the dark matter component of the filament that connects the clusters Abell 222 and 223, Dietrich and his colleagues took advantage of a phenomenon called gravitational lensing. They were able to determine the extent to which the supercluster distorted galaxies, and with that information, they could plot the gravitational field and the mass of the Abell 222 and 223 clusters. "It looks like there's a bridge that shows that there is additional mass beyond what the clusters contain, the clusters alone cannot explain this additional mass," Dietrich said.' Article in nature is here."

grouchomarxist (127479) writes "Microsoft is considering selling the Zune subsidized like a cellphone, according to this excerpt on MarketWatch from a PC World magazine interview with Microsoft's Zune marketing director, Jason Reindorp. According to the article: "The spokesman said that Microsoft first considered the cellphone-like distribution plan after seeing interest in its Zune Pass subscription service, which offers monthly paid access to songs on the Zune Marketplace, a competitor to Apple's iTunes store. Though he declined to say how many subscribers currently use Zune Pass, the spokesman said subscriptions rose 65% during January." The PC World interview doesn't appear to be available yet online."
