Plentiful quantum physics are based on probability. f.e. you have some single unstable particle. There is no law allowing to predict when exactly it'll decay (otherwise it would be no probability, but determinism). But there are brackets when we can expect it happening. 50% chance it decayed is at half-life time since the start of "clock". There is equation (from experimental data), allowing to calculate how much of f.e. 1000g of this substance will decay to 500g daughter isotopes and other products of decay (and another 500g remain original substance).. Probabilistic law can be used together with deterministic law. f.e. emission of photon (moment when it happens) from excited particle is ruled by probability, while energy released can be deterministic (peak +- some tolerance, again probability). Sometimes it's possible to cheat destiny/probability. f.e. decay of isotope by electron capture (when it's the only allowed decay mode) can be suspended indefinitely by ejecting (ionization) of atom.

Electronic circuit is modulating two or more alternating currents (AC) from two or more sine wave (or other wave) generators, typically. Prior sending them to transmitter. It's very similar to ADSR sound generation (in keyboards for instance), where input sine wave is multiplied by couple linearly interpolated params. It's completely different way of working than while summing frequencies/summing energies of photons at higher energies (in your example visible range spectrum). Energy of photon is calculated using equation: [math]E=h*f=\frac{h*c}{\lambda}[/math] If you enter yours 400nm and 650nm in equation, you will get: [math]E_1=\frac{h*c}{400nm}=3.1 eV[/math] [math]E_2=\frac{h*c}{650nm}=1.9 eV[/math] Add them [math]E=E_1+E_2=3.1+1.9=5 eV[/math] Reverse equation [math]\lambda=\frac{h*c}{E}[/math] and you will get maximum wavelength, corresponding to 5 eV energy, which is 247 nm. What you called "difference", in reality is summing energies of two photons. Exactly reverse. There has to be carefully designed set up which absorbs two photons, and release one photon, which has energy equal to energies of two incoming photons.

Riding dolphins I am not so sure about. I mean what would be the porpoise of that? Military dolphin https://en.wikipedia.org/wiki/Military_dolphin Dolphins were/are trained to listen device attached to them (turn left, turn right etc), commands send by radio. After attaching explosives to them, was meant to be used to destroy enemy ships quietly.. or to cause explosion/detection of mines..

HDD can be replaced to SSD any time. I would not buy laptop where you cannot replace disk to other. (and put old HDD to external disk adapter plugged to USB) The problem with SSD is that they have pretty low capacity. 2 TB+ in HDD is "normal", have couple such for years. I just saw that SSD 2 TB cost 850 usd here.. 1 TB SSD in promotion: 350 usd. That's 7 times more than for equal 1 TB HDD. You cannot compare price of 250 GB SSD to price of 2 TB HDD. Their parameters (capacity) are completely different. While price near the same.

What I meant is that even if cpu is slow, or hard disk is slow etc. nothing bad happens except user has to wait longer, just comfort of work is reduced. But if monitor has bad quality, it might result in physical damage of eye. With CRT being the worst, as they can emit x-rays. For obvious reasons not used in laptops. But I have seen some crappy laptops, that even a few second look at them 'hurt' literally. And can't think of using them on daily basis. What I meant, don't save money on your health. Worth to mention electronic paper, which switch content, when device has to display something else (f.e. next page in ebook) https://en.wikipedia.org/wiki/Electronic_paper Which is completely different approach to display, than CRT/LCD. "Many electronic paper technologies hold static text and images indefinitely without electricity." That feature is probably wanted the most by old people, who don't remember keyboard layout, and gamers, who like to play at night, with all lights off. WSAD any 3D game player remember, but often it's difficult to hit special rarely used keys (when all lights are off, and the only source of light is our monitor). But who is planning it in advance while buying laptop..

Acceleration from v=0 to v=0.999c would be taking a long time by itself. For exercise calculate how long approximately it would take with a=g=9.81 m/s^2 and how long it would take with 5g, 10g for example. Acceleration with constant a=10g would be pretty unpleasant for astronauts. Not to mention they would not be able to move and do anything. Significantly exceeding these values would kill living organism on board. The most of people lose consciousness between 5g-10g. Special Relativity is widely used while calculating decay of unstable particles, unstable isotopes, and high energy physics to calculate particles created during their collisions, and matter, antimatter creation and annihilation.

He has 2.124 millions views. His YouTube channel has adverts enabled. YouTube pays ~$1 per 1000 views. So he already earned approximately $2k, just on this video. Anyway, it's quite entertaining. Couple things for consideration: - it appears to be made of Aluminium, when piece of metal is moving near magnet (or vice versa), there is created eddy current in metal. Like we can see for example here: I would ask him to make it with plastic and wood, to see difference. - near side of wheel is not connected to far side, ball made of iron is conducting current, bridging them in one place. The other one might be construction, or nothing at all, or hand watch battery somewhere installed creating current in whole construction. - because of placing ball on the left side of wheel, that part has higher mass, than right side. - we don't know what is air circulation near device. I would ask him to recreate it in vacuum, to see difference. If it's not real stationary magnet, but electromagnet, just colored to pretend magnet, pulsing on and off, it would be attracting and repelling (or releasing) ball in wheel (and perhaps eddy currents slowing it down for a while), so one side has higher mass, than the other, causing it to move..

I especially pay attention to LCD screen quality. As it's what you will be watching all day long. Cheap LCD are bad for eyes, and watching them all day long is a real pain. If I would be buying laptop today, I would have to look at it while it's turned on with OS loaded, to see whether LCD/LED/OLED has good quality image.

Small cost = a lot of compromise in quality and performance..

No, I took 91% from https://en.wikipedia.org/wiki/Cotton "The chemical composition of cotton is as follows: cellulose 91.00% water 7.85% protoplasm, pectins 0.55% waxes, fatty substances 0.40% mineral salts 0.20%"

And it's wrong result. 2.22 g of carbon / 12 g/mol = 0.185 mol (all C) / 6 (atoms of C) = 0.030833 mol * 2 * 14 g/mol (of N) = 0.8633 g of N which is the same as 2.22 g * 0.389 = 0.8633 g Going my initial thought (and independent Itoero from post #17) 5 g * 0.91 (91% of cellulose in Cotton) = 4.55 g / 162.144 g/mol = 0.028 mol * 2 * 14 g/mol (of N) = 0.784 g of Nitrogen needed. (difference is caused by initial multiplication by 0.91) Although I don't understand why you calculate amount of Nitrogen, while we're interested in nitric acid in the first place. 0.028 mol * 2 * 63.012 g/mol = 3.53 g of HNO3 needed. ps. 72+80+10 = 162 You said, it's not even closer to that value. I was not talking about mass of whole long chain compound, but single monomer unit. Itoero interpreted it correctly.

+1 What is product of KNO3 and H2SO4.. ? And in what proportions they need to be.. ?

Can I answer by PM.. ? To not influence answer by OP.

If you have 5 g of cotton, how many moles is it? If you have 50g KNO3, how many moles is it? If you have 80ml H2SO4, how many moles is it? If you have 1000 g of water, how many moles is it?

From http://www.drivers.com/download-help-sdu.php "Full access to over 600,000 Software Drivers" Again, proved wrong. There is approximately as many drivers are there is device models, multiplied by number of OS APIs for drivers (driver developer kit, DDK, or Windows Driver Kit, WDK). Multiplied by 2 (32 bit/64 bit). Or so. f.e. https://en.wikipedia.org/wiki/Windows_Driver_Kit#DDK_Versions Generic drivers are provided by Microsoft, not device manufacturer. f.e. generic gfx driver does not have GPU acceleration, just pixel-by-pixel draw lines. To have proper full speed of hardware there is needed proper driver from device manufacturer. They know how to code their hardware, after all they made it. All secrets of HW.

Pressing negative vote, means "we don't agree with what is said in post" (partially or totally), without going into senseless discussion "why it's wrong" (objectively) or "why in our opinion it's wrong" (subjectively). (As you ignore any reasonable argument or question. That's not blog, nor preaching zone. It's discussion forum) Reversely, pressing positive vote, means that somebody agrees with post. So far you have 19 negatives. 19 people disagree with you. Something like 16 of them are not from me. Unlike you, I have 390 positive votes. If you would be less "angry" (for whatever reason, you are acting like that), and didn't start with this ridiculous "I am the most intelligent organisms on the Earth", that was deleted and end up in trash, perhaps people would like to hear what you want to say. You missed your unique chance for making good the first impression. Not smart at all..

I wrote PCI card driver ~15 years ago for C-Media sound card, yet another I forgot name, some version of Sound Blaster, and 3D gfx card. Different models have completely different hardware registers. At that time sfx card had 1 channel or 2 channels, one for each speaker. Now modern sfx card can have multiple speakers simultaneously connected. I have here 5 speaker system. Method of programming them depend on how they were designed by engineers. Sound cards with DMA for instance, require setting up address of block next to play each time when currently played block is finished (double buffering), properties of sample (8 bit signed, 8 bit unsigned, 16 bit signed, 16 bit unsigned), frequency, volume, and the length of data in block. The shorter length of block, the more often we have to provide new data, CPU usage will be higher. It's all done inside of interrupt routine. CPU normal work is suspended, all CPU registers stored, and interrupt routine installed by driver is called. (similarly multi-threading is implemented) Sound cards without DMA, are (were) (because they probably all extincted, not produced anymore) programmed completely differently. There is register in which there is write-only current sample data. Programmer has to write it, wait exact number of cycles, write again, wait (cycles), write etc. in loop. Or utilize other interrupting routine, just to feed HW register with new sample. (on Atari 8 bit for this purpose there was utilized DLI (Display List Interrupt), that was called 15625 times per second or so) On the top of this there is running the main virtual channels mixing routine, which is mixing f.e. 32 virtual channels to f.e. 2 physical channels. The more speakers sound card can handle, obviously the more registers present. So don't tell me that driver good for 2 channel system is good also to multi-speaker card. It's plain gibberish. Drivers are in bigger packages for convenience of end users. User is going downloading one huge driver archive. Does not have to bother to find exact card. It's leaved to installer to pick up right one from library.

1) You're not doubt very articulated person. Which suggest that you're rather humanist than logically thinking mathematician kind of people. 2) Showing that proprietary security system of particular company has been compromised, does not mean entire world suffer for this. After revealing vulnerability their authors had time to fix issues. In your ignorance, you're expanding that if some virus existed in the past, it must work everywhere, and forever. 3) You cannot send me any such packet as you claimed, because simply I don't use DHCP.. 4) Intercepting DNS servers, compromising router/modem, replacing DHCP settings, is the easiest way to get in, but it's easy only on paper (that you read about subject). You're making assumption that every body in network use DHCP. That's not always the case. Only ignorant use DHCP. And you need your own *DNS server* (if you're professional), made in C/C++, which will be nothing alike standard DNS server exe (or you simply will have no real time access to what somebody is searching). 5) My "challenges", as you called them, have to show that you just looked up terminology in the Internet, without having the real experience in subject. You refused to perform any of them, because it would reveal my assumption. 6) Challenge (again): which Windows API C/C++ function you have to use for installing key-logger on somebody machine.. ? 7) Making fake banking website is months of planning, testing, and you have to start from creating your own bank account, to see how it even looks like. And replicate every page, every functionality. Claiming it's fast and easy, is ridiculous. Every bank has different security. Intercepting bank login and password, will just show you what money somebody has on it. You won't be able to use them the most likely. There are needed temporary security codes etc. To see what money somebody has on bank account you dont have to get login and password, just search his/her mailing box for per month send bank statement.. Couple banks here is using codes send to mobile, generated during transfer attempt. User has to enter code send to mobile (proprietary app) inside of banking account website. Others have codes on scratch card. Even user has no idea what are they, until revealing code. Try to bypass it. But you have no real experience, so you miss the all details. Mythbusters security system compromise episode:

That's not possible. Each desktop PC and laptop is different. Different hardware, thus different drivers installed, and different software installed. In my apps I don't recall serious issues with different OS version, other than not being able to use unavailable functions (which means unable to even run app, with unresolved DLL entry (if they are static linked) ). There would have to be made one desktop, one laptop, one OS, for your words to be true (like in game console industry). Compatibility issues are inevitable as drivers manufacturers are not Microsoft usually. And even if they are MS, they are not one person that know everything. Corporations, are complete nightmare for anybody wanting to do with them, or to fix something in their software.. They have no bloody idea what they are doing (as they are thousands of people), who is doing, what is doing, lack of (or bad) communication, constant flow of employees, in and out. Nobody is forced nor encouraged to place their desktop software on Windows Store (unlike Apple Store for iPhone apps) Software that runs on PC, won't run on mobile phone. And vice versa. They wish to do. That's good only to Microsoft. There is no advantage for users. They wish everybody on the world have to pay them per-month.. For example, what security improvement do you have in mind? For example, what performance improvement do you have in mind? If there is 1 million of people suggesting something, vote of 1 of them has 1 per million "power", meaning it will the most likely be ignored. You have been working on Windows 10? Right. Then no surprise you advertise it.. I bet, if I will ask the basic question about programming Windows C/C++, you won't be able to answer.. Similar like with physics/quantum physics questions. Try f.e. booting up Amithlon on any Intel x86 1 GHz+ machine.. The faster CPU are build, the more lazy programmers become. Or companies hiring them, the less demanding.

The Angry Intellect, is there a thing that you *really* know? I bet, if I would ask you to write DNS server C/C++ code, you would not have idea where to start.. Show me how are you making TCP/IP tunnel in C++ for a start.. Building magnetic card reader should allow only as much characters as is needed. Which means sending entire source code is not possible. Some badly designed systems might exists, but are minority. As it's easy to spot issue. Jumping from building security system to intercepting DNS - ridiculous.

If Jupiter would be slightly further, or have smaller mass, smaller gravity, instead of belt of asteroids between Mars and Jupiter there could be formed yet another planet. It's not predestined that such planet won't appear in the future. Objects in cosmos come and go, some are intercepted, other ejected. Read f.e. about runaway stars and hyper velocity stars ejected by black holes: https://en.wikipedia.org/wiki/Stellar_kinematics#Runaway_stars If such object would fly through solar system, in the nicest scenario, planets would be ejected, and captured in the future by other star (ruining your 9 planet model). Current methods of detection of planets are working good with massive planets like Jupiter+, that are very close to their star (so it trembles a lot). These systems are nothing alike solar system. BTW, there is only one Solar system. The one with the only one Sun and Earth. Other planetary systems will have different names. https://en.wikipedia.org/wiki/Planetary_system

Movie or image is presented to group of people who are inside of MRI or other such device. Then from data from MRI computer algorithm is trying to figure out what people watched.

Once more time you show lack of knowledge in physics. Amperage without mentioning duration (time) is not enough data. You should ask "how long current should be flowing?". Then we would know, you know physics. If you have 10 kA, for 15 ns, how many electrons is it.. ? So far you are the one who has nothing to offer. Instead of answering questions proving you are knowledgeable, as you claimed, you preferred to refuse them. Simply because you have no idea what we are talking about.

Quote from your "blog": "I have done some personal experiments on myself over the years using different chemicals & TDCS (Trans-cranial Direct Current Stimulation)." Apparently at too small amperage.. Try 10 kA the next time.

Oh, really.. ? Then you should have no problem telling us what is energy released by decay of anti-matter anti-Carbon-13.. ?
