At 15 x 10^6 K, the sun's core is hot indeed.
At 100 x 10^6 K, the temperature required for deuterium-tritium fusion, tokamaks are a bit more impressive.
Also what is impressively low is not the temperature of the sun's core, it is the energy it generates per unit of volume.
Apple even creates open standards for the web. For example, Apple began with a small open source project and created WebKit, a complete open-source HTML5 rendering engine
The small open source project is KHTML, a complete open-source HTML(4 at the time but I suppose it reached 5 now) rendering engine. Instead of improving it, they forked. Which is legal and ok, but not enough to recognize Apple as a standards creator on the Web.
Exactly. They can't just "have" Android because it is free. They have to develop a device, they need people who know how to do that. Now they can make an Android-like.
This budget is probably to hire someone to coordinate the goodwill and efforts of people who are already funded by other means. 1 million means a 5-10 people team to do the work that no partner wants to do. That is not nothing. This is not the main gear, this is the grease that will make them turn. And sometimes, a big multi-billion project fails exactly for the lack of these small drops of grease.
The resulting fusion reaction will release many times more energy than the laser energy required to initiate the reaction. Experiments conducted on NIF will make significant contributions to national and global security, could lead to practical fusion energy, and will help the nation maintain its leadership in basic science and technology.
The goal of this kind of experience is geared toward energy production. Granted, this is not a prototype power plant, but one could consider the lasers used there as a prototype for elements of a power plant.
The summary also is funny in how it understates achievements of fusion research. I remember a physicist saying "The Sun ? Pfah ! Too cold and too inefficient ! If we were to reproduce the conditionss in the sun, we would never get anything that would interest industries !"
They still lack a medical lab. Claiming condoms worsen the AIDS problem is the modern-day equivalent of Galileo trial. Except that this time it kills thousands of people.
For the record, this kind of situation is what is currently practiced in France (since about 20 years now I think) and the abuses have been exactly what is predicted here.
There is a big difference between making one single mistake and having a risky attitude. This is especially true for people who are at a hierarchical higher level than the IT people in charge of the security.
March 23 (Bloomberg) -- The U.S. Navy, after nearly six years of warnings from Pentagon testers, still lacks a plan for defending aircraft carriers against a supersonic Russian-built missile, according to current and former officials and Defense Department documents.
The missile, known in the West as the ``Sizzler,'' has been deployed by China and may be purchased by Iran.
``This is a carrier-destroying weapon,'' said Orville Hanson, who evaluated weapons systems for 38 years with the Navy. ``That's its purpose.''

The missile cruises at 5 m above the sea, can go quickly from subsonic to supersonic and can perform various evasive maneuvers. When you think about it, it is quite easier to design a missile system than an anti-missile one. I am not leaving in an alternate universe : I read the Russian comments on laser-based antimissiles and on patriot anti-missiles and it is very clear that one of the selling points of the latest Russian missiles is that they can bypass these systems. One of the reasons why the starwars project was deemed useless was the ability by Russians to design a missile that would go to ballistic mode (hence, stop engines) at the very beginning of their cruises, making them quite harder to detonate through lasers (lasers usually detonate the propelling fuel, the warhead is too protected to reach)
Yes, the things are different. But OSS counters the argument "You can't make a living by giving away stuff.". Yes you can, but it takes a clever businessman to manage it. No one claims anymore that OSS is something you can easily dismiss, but do you remember how it was 15 years ago ? Nowadays, people who give movies or song for free only encounter marginal successes. This doesn't mean the Google of online music won't appear.
If you sell sand $100/kg in the middle of the Sahara it is not a workable business model. Even if you have a mine employing 1000 people, protecting this business plan would be silly. Well, selling $30 DVDs that can't be read easily whereas it is free to download a rip that provides more functionalities is exactly the same situation.
This is, however, the sad truth. Aircraft carriers nowadays are very vulnerable beasts. I read that it is acknowledged that in the case of a conflict against Iran, all the US navy in the Persian Gulf would be sunk within hours. One may joke about Russian tech, but they are good at one thing : building missiles that bypass American protections.
Homo oeconomicus doesn't exist. The models used to defend or criticize free market, minimum wage, healthcare, etc... are over-simplified and often in a biased way. They often consider profit as the only drive for human action. That is why so many people rely on the historical examples. These examples show that minimum wage and healthcare did not cause crisis. From there, one can try to find a reason as to why, but pretending to be able to predict what will happen after the introduction of this or that measure is just preposterous.
Instead of using that timber for paper, it'll be used for lumber or for biomass electricity generation (which has a net zero carbon emission).
Paper production has a negative one. If that is your only metric, paper wins. Anyway the most efficient way to capture CO2 that we know today is to grow tree, cut them, repeat. Activities that involve that are good with respect to CO2. Nasty chemicals are indeed another problem.
Hehe, but if you lose some brain part (as is abundant in medical literature), what do you care if new neurons are generated inside your head or inside a new one and then transplanted ?
...the use of owning 1000 Facebook IDs ? What is the idea ? Who would want it ? I may be dense but appart from spam senders I don't see the use of this.
blood-brain barrier ? What makes you think a cure to cancer must be blood delivered ? You know, the brain isn't a mystical box, we know how to remove big chunks of it without much damaging effects, we know very well a lot of its mechanisms. So many handicapping dysfunctions happen there that there are probably a lot more resources invested in brain studies that in any body part. Do you have any reason to expect brain cancers to be the last type of cancer cured instead of the first ?

That would mean that a volume the size of a swimming pool is required to fuel a regular home.
Peak power production in the Sun has been compared to the volumetric heats generated in an active compost heap.
Bwahaha, I love science

When was the last time America fought openly an army equipped with state-of-the-art Russian equipment ?
There is little sanity and a lot of craziness coming out of the discourse on X, and we're going to see it affect us
Corrected. Replace X with "IP", "climate change", "economy", "healthcare", "drugs", "terrorism", "the tube network"...

Anyone can be fired for a bad day.

Keep in mind that this comes from the man that said condoms worsen AIDS prevention in Africa (a declaration I consider liable in a court of justice)

Yeah, you can bet that these computers are stolen for good now...
First time I've seen something like this, where Obama is more hawkish on a military matter than Bush ? Man that seems wierd...
Considering that he asked for other countries advices before deployong this I don't consider this as a hawkish move...
Note that technically, one could put a conventional warhead inside a ballistic missile. We just identify ballistic with nuclear out of habit
Hehe, but if you lose some brain part (as is abundant in medical literature), what do you care if new neurons are generated inside your head or inside a new one and then transplanted ?
All these things seems related to "having a facebook account", hacked or not.

They do what you tell them to do. They don't tell lies. They are unforgiving but it takes a human to make a computer fail.
