Most people think that scientist are strange people who have amassed a huge amount of very precise facts about an extremely specific field, some of which might be useful (facts or fields), but most of which are useless to the common people. The prototype is the scientist lady in the TV series "Bones". Scientists are assimilated to dorks who have not only not an ounce of creativity in them but also no social skills.
In reality scientists need to be extremely creative in their work, and need to have the humility to accept that they know or understand only a tiny amount of the world that is around us. It is very easy and quick to tread into the complete unknown. We cannot at present even reconcile the most established theories we have about the way the world works (relativity and quantum mechanics).
No, that is easy. Most paths in science have never even been tried.
What is hard is to find a path that leads to somewhere. Then just as hard it getting the somewhere you discovered to be accepted by the scientific community. Think plaque tectonics, relativity, quantum mechanics, even something as fundamental as cosmology, and so on.
First you need a friend with an Apple computer and OSX 10.6.8 or later installed. Then you can download the 10.8, 10.9 and 10.10 version of OSX for free on the Mac App Store. If you do not own Apple hardware but want to try these OSes anyway in a VM for instance, it can get a little involved but is generally doable.
Contrary to a somewhat popular opinion among car hotheads, the least reliable component on any car is usually the driver. While on the road, drive safe. If you want to have fun with your car besides enjoying the scenery, go racing.
Underground/Subway/Metro or some other specific lines with zero interconnection running as a loop, yes. They are all akin to a long, horizontal elevator, with lots and lots of sensors and other feedback systems built into the track. They make a lot of sense because they carry a lot of passengers over short to medium length lines over the very same tracks all the time. The longest automated network is the Vancouver skytrain, which is about 70km long.
General-purpose train lines, with something unlike single-purpose engines running on open tracks with interconnection ? The page does not list any. It is still too difficult for automated systems.
Nearly all of the development tools of Linux are available on OSX via ports, brew or simply compiling oneself. Even fairly advanced stuff like valgrind. There is no shortage of cross platform GUI toolkit like Qt.
In what way is OSX crippled as a dev box ?
Since OSX 10.4 or so, it has been relatively easy to install OSX on any PC. So if one is curious and wants to try the ecosystem, one can do it at a very low cost, that of one already existing, partitioned PC, or a virtual machine. This does require some technical skills, for sure. In recent years it has become easier, not harder, to do so.
This usually is a fairly smart move on Apple's part. This test will usually convince people who try it that they can trust Apple to be their provider for their next laptop purchase. In this department, their approach truly shines.
From an ideal standpoint it looks as if super-intelligent kids is something every parent would want. However there are some drawbacks. First, IQ is only a rough measure of intelligence, there are many factors involved and success in life is not immediately linked to IQ. See Unabomber, etc. Also super intelligent kids may not be that easy to handle. They typically hate school and may actually do poorly in school. They demand much more attention from parents (more activities, more time with them, etc). There is plenty of evidence that IQ is also linked to the environment kids grow in, so simply selecting the gene stuff and thinking this may be enough will not work. Intelligence is also linked to curiosity and independence and so perhaps to more risky behaviours. Finally there is a correlation with very high IQ and some severe forms of mental illness.
All in all, there is a cluster of reasons why the average IQ of the population is 100. High intelligence is not always that comfortable. Think of Sir Winston Churchill, hero of the battle of England, most effective Prime Minister in a time of war, Nobel prize winner in litterature. He had severe depression all his life (his "black dog"). I agree we should raise the general IQ though, cautiously.
Bill Gates claimed to be doing that that (among others) and he is not finding it easy.
John Bardeen has won two Nobel prizes in physics. The first for the discovery of the transistor, and the second for the BCS theory of superconductivity. Read the page, it is highly entertaining. Bardeen was very unassuming but clearly a genius as well.
Tesla cars are interesting, but their impact is currently limited. The cars are simply too expensive. We'll have to wait and see if the impact of Tesla can change the industry. Other Elon Musk endeavours are also too early to tell. SpaceX is already going to space, but as others have commented, low Earth orbit is not really space yet. This is the cosy neighbourhood of our home. Getting to Mars and beyond is currently nothing but a dream.
It is too early to compare Musk to Jobs. In spite of its many documented faults, Jobs had the drive to start and set Apple on the path to spark the personal computer revolution in the 1970s, particularly with the Apple ][. Recent Apple products are quite nice for some but this is the earlier feat that matters. Many other companies tried to do the same thing at the same time and did not meet the same success. The IBM PC was a late comer and got started after Apple and others had demonstrated that producing personal computers made business sense.
The only reasonable post in the entire thread. Please mod up.
The spin of a photon is a boson is always 1. That's not too hard to transmit. Approximately 0 bits are needed. Furthermore, the momentum of a photon is always h\nu, with \nu the frequency. So if you know the frequency of a photon, you also know its momentum, with another 0 bit to transmit. Finally I don't think a photon can have an orbital quantum momentum. Electrons can have those. That is unless things have changed since I last took a class on quantum mechanics.
In other words the summary is the worst I've seen in a long time.
