Newton and Leibniz may well have invented calculus independently. And I'd like to know which version you use, because Newton introduced the product rule, the chain rule, the notion of higher derivatives, Taylor series, and analyticity.
http://en.wikipedia.org/wiki/Calculus We don't use his notation, but that is a small difference.
You do a real injustice to suggest that math was "his field", as he invented calculus to help him invent classical mechanics. He invented F=ma. Not until Einstien 200 years latter was that improved upon significantly. He invented color theory. Which led him to construct the Newtonian telescope to remove the chromatic aberration his color theory implied. And, thanks to his use of Newtons's rings to measure the quality of the mirrors he was grinding to build his telescope, they were the best telescopes available in the day.
If he was not a Genius, then there have never been any.
Creating a 3D representation of data might look cool, but it's just not efficient to work with for any amount of data beyond 2-3 items. See: Win-Tab in Vista, Stacks in OSX. It's not that we need better ideas for how to represent data in 3D, rather it's a physical limit that we need to accept and stop trying to do it "because we can.
I won't argue that it has not been done very well yet, but I am not sure it is because it can't be done. You could make a similar argument that adding color to the desktop is pointless, but it can be used to add information. Perspective transformations, transparency, and other effects might well improve the interface even though they exist in 2 spacial dimension.
Some photons have a wavelength smaller than the wavelength of an atom. But none of the ones I'm seeing now do.
Laser red wavelength = 632 nm.
Helium atomic radius = 31 pm.
I'm not positive that the Laser Writer was the first laser printer - but it sure did work well. I think this was critical in addition to the applications you list.
It was a bit cryptic, but from compiled app on the sym to signed and uploaded app on the store was less than 4 hours in my case. Then about 4 days before it was accepted and on sale. But, hey if you bill $500 per hour, then you don't need to write iPhone apps.
Have a look here: http://antwrp.gsfc.nasa.gov/htmltest/rjn_bht.html
Regarding the gravitational wave detection, that would be for colliding black holes. The "ringing" that would result should distinguish between black holes and other high density objects. The upgraded LIGO might see these collisions.
I suggest that gravitational waves might be a way other than Hawking radiation. And depending on what you mean by directly detect; if we get a nice image of something behind the black hole that would be good too. ASAIK the only issue remaining was could the mass be some exotic form of matter like quark soup. And I thought this had been resolved already, so I'm not sure what is supposed to be new in the report.
The next major case, Sega vs. Accolade, created a much stronger precedent because there were no fraud issues involved. In a similar manner to Atari, Accolade reverse engineered Sega's Genesis technology to discover how to make games for their system. Accolade then created a book with the relevant (and non-protectable) elements of Sega's technology, and passed the book on to their developers. These developers created a new game, Ishido, to compete with Sega's games.
In deciding the case, the court looked at many factors (including public policy concerns). In the end, the judge decided that reverse engineering software for the sole purpose of creating a compatible package is an acceptable use (under the "fair use" doctrine). In addition, the appeals court stated: "[i]f disassembly of copyrighted object code is per se an unfair use, the owner of the copyright gains a de facto monopoly over the functional aspects of his work - aspects that were expressly denied copyright protection by congress" [1]. Thus, the court decided to adopt the policy encouraging competition (as opposed to IP protection) in the software industry.
I did some of the audio portion of the reverse engineering for Accolade. I miss having to use an oscilloscope in the course of my software work.
Even if he got fired, he'd almost certainly find a new, and probably better job.
Maybe. When I hiring software engineers at Razorfish San Francisco, we interviewed http://en.wikipedia.org/wiki/Jacques_Servin around 1998 I think. Google was fairly new to me, and I checked his name. We did not hire him.
No doubt he found a much better job.
Preschool Adventure seems to get good reviews. And at least with my boy he completely gets the touch interface. He navigates to the apps that he likes. He can work the iPod music app. He can work the camera. And there is a little sample app called SpeakHere - he records and plays back.
Have you tried an iphone with a toddler? I have not tried to teach letters yet, so the keyboard might be an issue - but all he does on a real keyboard is bang away.
Ignore the negativity here - not likely they have kids. My 2 year old son only wants to do what the bigs (big kids) do and that includes computers. But his little fingers easily take the keys right off the laptops. And I think he will eventually break the display so I try to keep it away, or only let him use it while I am right there. There's no end to what he likes on Youtube - particularly Tractor videos. I don't think I will get him an eePC for a few years again because of the keys. But, he is quite good with my iPhone, so I might get him a new iPod Touch. It is not so easy to break, no keys, the new one have little speakers and my little one has figured out how to start his favorite music.
Classical Maxwellian electromagnetism is compatible with quantum theory since it's the formal classical limit of QED, but that doesn't mean that everything in QED has a classical analogue.
I can't say otherwise for sure, but I think it might only be one way; that not everything in QM has a classical analogue, but that every classical trait has a QM analogue. Mass, charge, momentum, angular momentum, position... all having QM equivalents.
I actually wish I had the time these days to follow up on what is said in Baym to how far off my thinking is...
The positron-electron releases far more energy than the sum of the kinetic energies of the particles unless you get them going REALLY fast. Most of the energy comes from non moving-charge processes.
I do know the difference between mass energy and kinetic energy.
Also note that neutrons and anti-neutrons annihilate. Neither is charged. Yes, they're both composed of charged quarks, but the energy released is far more than the kinetic energy of any of the constituent particles.
I assume you mean the kinetic energy of the N ~N; I am thinking that the motion of the quarks may well be the source of the photon.
It's not particularly insightful to claim that you can't create EM radiation without charged particles since we don't know of any uncharged fundamental matter particles (yet).
I can almost read this to say that Maxwell's equations are not insightful. They seem to be derivable from QM with a little help from Dirac. Do tell me what you get when you shake a neutrino.
I'm looking back into my copy of Baym "Lectures on Quantum Mechanics" in the chapter on Interaction of Radiation with Matter and he says, "Spontaneous emission is just the quantum mechanical version of the classical phenomenon of radiation from an acceleration charge." Baym later compares the same spontaneous emission work to pair/anti-pair production. I gather that the accelerated charge in the quantum sense corresponds to a change in the expectation value of the momentum of the particle. But, it would take a fair more amount of time to convince myself one way or the other. But it is my understanding that Maxwell is entirely (with minor modifications) compatible with QM which makes me think that I am not that far off.
You link to Technetium-99m which is an excited nucleus that undergoes gamma decay. And you claim that there are no moving charges by which this gamma ray is generated. I link to A Brief Review of Nuclear Physics http://galileo.phys.virginia.edu/classes/252/Nuclear_Notes/nuclear_notes.html and quote the section on gamma decay
gamma-decay
The gamma rays are just high-energy photons, of order 100 keV to a few MeV. Emission of gamma rays is similar (but at much higher energies) to emission of photons by excited states of atoms. The nucleus can be excited by having just emitted an alpha or beta, or by colliding with another nucleus, or being bombarded by neutrons, say. All these events can lead to a nucleus in which the charge distribution is oscillating, and electromagnetic radiation ensues.
Same idea for the positron - electron collision - those are clearly not at rest.
If you choose to correct Prof. Fowler on his understanding of nuclear physics I hope you will post the dialog here;/. is not as funny as it once was and I miss those days.
Just a guess on Mail and iTunes: because you might get mail and want to see it, and you might be playing tunes and want them to keep playing. I don't know about iCal - because alarms still pop up even if iCal is not running. With iPhoto, Disk Utility and Calculator you really are done when you close the window. I do get your your other points...
If I recall you need PDE for any wave equation ( of more than 1-D? ). Maxwell's equations are pdes. This is second year physics for all Caltech undergrads. Phys majors will see Navierâ"Stokes in the third year of undergrad.
That's fine, but what about when you reach the end of the process and the atoms/molecules start to cool down? Unless you separate them out, they're going to start to react.
Yes, however they will react to form the lowest energy compounds available which in turn should be fairly nonreactive. I expect that air or perhaps O2 will be added to the plasma which will help oxidize anything that can be oxidized.

The codesigner only runs on Intel. Xcode and the rest of the iPhone sym (at least v 2.0 ) ran on PPC if you made the effort to install it.
