Ideal point light source, is emitting photons in the all directions, and obeying inverse-square law: [math]P=\frac{P_0}{4\pi r^2}[/math] P0 is initial power of star, in Watts = Joules per second. P is power per area unit here on the Earth, in Watts per meter square = Joules per meter square per second. https://en.wikipedia.org/wiki/Inverse-square_law So, the larger area of device, the more photons can be reflected/refracted by lens, and then absorbed. Star that burned entirely from our point of view is invisible. It can still be seen burning, from other galaxy "behind us", because "final" photons didn't arrive there yet. But they will see much smaller quantity of photons per their area unit. Star that is invisible, it's invisible in 400nm- 700nm visible photon spectrum range, it can still be seen in f.e. infra-red or radiowave spectrum range. It depends on temperature. Hot body sends higher energy photons. See black body radiation article. https://en.wikipedia.org/wiki/Black-body_radiation You can't see that tea/coffee is hot or cold. It's temperature is ~90-100 C (373.15 K). But if you would use infra-red camera, you would instantly see it as red-yellow-white colored on the display, significantly hotter than surrounding environment (f.e. 25 C). The hotter body, the more energetic photons emitted.

Do you heard about lizard regenerating their tails? https://en.wikipedia.org/wiki/Lizard "Many lizard species (including geckos, skinks, and others) are capable of shedding part of their tails through a process called autotomy. This is an example of the pars pro toto principle, sacrificing "a part for the whole", and is employed by lizards to allow them to escape when captured by the tail by a predator. The detached tail writhes and wiggles, creating a deceptive sense of continued struggle, distracting the predator's attention from the fleeing prey animal. The lizard will partially regenerate its tail over a period of weeks. A 2014 research identified 326 genes involved in the regeneration of lizard tails.[8] The new section will contain cartilage rather than bone, and the skin may be distinctly discolored compared to the rest of the body."

That applies to almost the all users making threads in Speculation forum... So maybe some native English speaker would make thread and pin it "What scientific theory does mean".. etc. How to make measurements.. how to verify equations are correct during experiments, etc.

You have sci-fi movie vision of what "dimension" is.. "the dimension of a mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any point within it" https://en.wikipedia.org/wiki/Dimension Chess analogy: Say you have chessboard, there are 2 dimensions with 1st dimension 1,2,3,4,5,6,7,8 and 2nd dimension A,B,C,D,E,F,G,H possible coordinates. If one would add yet another dimension to chessboard, figures could move up and down. f.e. a,b,c,d,e,f,g,h possible values. Figure at A1a would not beat/overlap figure at A1b. With 2 dimensions A1 overlap A1 (without a and b in 3rd dimension).

Nonsense. You forgot to mention the one important rule in your game.. The way you described above, one could join 1-4,2-5,3-6 (or 1-4,5-2,3-6). And have 3 total length. But there are missing 4-5 and 2-3! Therefor the way you explained game in #1 post, the correct answer is 5.

Noble gases are not chemically reactive. Difficulty in going them into reaction explains why the first noble gas compound was found just in 1962. https://en.wikipedia.org/wiki/Noble_gas_compound Half-life of the most stable Radon isotope is just 3.8235(3) days. https://en.wikipedia.org/wiki/Isotopes_of_radon

Isn't (x+y)/(x-y)*(x-y)/(x+y) equal to LaTeX: [math]\frac{x+y}{x-y}*\frac{x-y}{x+y}[/math] ?? Maybe some parenthesis missing somewhere? Which is equal to: [math]\frac{x+y}{x+y}*\frac{x-y}{x-y}[/math] [math]1*1[/math] [math]1[/math] (as long as no division by 0) f.e. if I make OpenOffice SpreadSheet with A1=1000 B1=500 and C1=(A1+B1)/(A1-B1)*(A1-B1)/(A1+B1) Result is 1. If I make A1=B1=1000 f.e. OpenOffice complains there is division by 0. They will be z'=1/z or z'=z-1

Edible dormice: High food availability slows down cell aging http://www.vetmeduni.ac.at/en/infoservice/presseinformation/presseinformationen-2016/edible-dormice-high-food-availability-slows-down-cell-aging/ This is worth reading and rechecking by other researchers, and with different kind animals. More scientific paper http://jeb.biologists.org/content/219/16/2469 Best Regards!

Corrected version: [latex]f(x)=(1-sgn(abs(x-a_1)))*b_1 + (1-sgn(abs(x-a_2)))*b_2 + .... + (1-sgn(abs(x-a_n)))*b_n[/latex] a1....n are indexes. b1....n are values from sequence.

[math]f(x)=sgn(abs(x-a_1))*b_1 + sgn(abs(x-a_2))*b_2 + .... + sgn(abs(x-a_n))*b_n[/math] a1....n are indexes. b1....n are values from sequence.

Sequence 1,1,1,1,2,1,1,1,1 assuming the first one is x=0 could be received with [math]f(x)=2-sgn(abs(x-4))[/math] https://en.wikipedia.org/wiki/Sign_function x must be integer.

I have isopropanol in HDPE bottle (bought in electronic shop).

I am drawing sketches sometimes, but for myself. To first know what to remake in 3D application. I was using f.e. https://en.wikibooks.org/wiki/LaTeX/Mathematics https://en.wikibooks.org/wiki/LaTeX/Advanced_Mathematics

I would not use them even in reply on this forum... It's even more hassle: you have to paint, take photo, transfer data from digital camera/smartphone, or scan (if you have scanner).. When in application it's easier. You can make error, and fix it, while on paper, you would have to start from scratch. Indeed. Use 3D application for such drawings. There is free Blender, there is NewTek's LightWave for $700 (student version is probably cheaper), Maxon's Cinema 4D, Autodesk's Maya, SideFX's Houdini, But these are more expensive.

Do you have your own Cholesterol checking machine.. ? If yes, you could make a series of tests, how Cholesterol varies in day, taking test per hour, or couple hours, or how it changes after eating certain types of foods. Record in Excel/OpenOffice SpreadSheet time and reading from device. And time and thing that you ate. And present results here. I saw on the net graph how cholesterol level changes (Y axis), with quantity of consumed green tea (X axis). You could verify observation made in this article on yourself. https://www.healthaliciousness.com/blog/How-much-does-green-tea-lower-cholesterol.php Links at the bottom of article also try to answer your questions.

Why unrealistic? Tritium is produced from Lithium.. Building fusion reactors will increase demand for Lithium even more. Neutrons are for free in currently existing nuclear plants.. So better to use them cleverly.

Did you try PHP image generation? http://php.net/manual/en/image.examples-png.php JavaScript could download file from some URL, but instead of "image.png", there is PHP script instead, generating image. To have it with .png extension, there is needed to modify Apache and/or PHP configuration file, which file types are processed by PHP daemon. This way user does not even have to know script is run to make image. (not really required, one can have "generate.php" script output PNG, as browser recognize image by header, the first line in script in the above link)

You don't need to do anything to make it happen. Free neutron decays to proton, electron and antineutrino, releasing 0.782 MeV per reaction with ~10 minutes half-life (~15 minutes mean-life). Mass-energy of neutron is 939.565 MeV/c^2 multiply it by 1e6 * 1.602176565*10^-19 to convert to Joules, divide by c^2, to have mass in kg: ~1.67492667626123E-027 1 g = 0.001 kg divide by 1.67492667626123E-027 gives 5.97e23 neutrons per gram Each one can release 0.782 MeV (782000 eV) per reaction. * 1.602e-19 (eV->J), * 5.97e23 neutrons = 74803398357 J Half on it will be taken by electrons, because antineutrino takes some energy. Alternatively you can subtract sum of mass of proton and electron from mass of neutron, in kg, multiply by c^2, and multiply by quantity of reactions.

In Standard Model quarks have >4 MeV energy/mass, while electron/positron have 0.511 MeV energy/mass. How can it not being conflict.. ? When there is obviously missing mass/energy. For example, the lightest meson neutral pion has ~135 MeV energy/mass. After decay it can create free electron and free positron, and they're accelerated nearly to speed of light. Electron or positron don't decay to neutral pion, nor any other meson or baryon.

If something extends lifetime from 70 years (usually wasted by ordinary people), to say 200 years, that's nearly 3 times more time to work on progressing even further. Using newly saved years to extend it the next few years.. But people have to work on it (physics,chemistry,biotechnology,medicine,rocket science,IT), in the first place.

Lithium-7 can be made from Boron-10 after neutron capture. B-10 + n0 -> Li-7 + He-4 + 2.795 MeV Also it could be made by from Helium-4 after at least double neutron capture.

That's what for he made thread about modifications of DNA, to fix damaged DNA.. To state it used to have during his yearly age.

Did you read this? http://www.pcworld.com/article/2984716/laptop-computers/how-to-transform-your-laptop-into-a-gaming-powerhouse-with-an-external-graphics-card.html It makes pretty little sense to me. You have to buy PCI gfx card, have to buy PCIe adapter (like this one http://www.ebay.com/itm/Laptop-Expresscard-34-To-2-PCI-E-Slots-Adapter-Notebook-External-PCI-Express-/222173937192 ), cost more than my desktop motherboard, have to buy external power supply, have to buy external LED/LCD monitor with large enough size say 24"+.. Then why bother and not to buy the real desktop.. ? At home, I am using dual-LED 24"+ monitors, with Core i7 quad-core desktop.

If you don't know, and don't want to know math, you really won't understand how these things work.. How to explain somebody who does not want to know math f.e. nonlinear electronic element? You probably don't even understand what it means.. Sensible book would show graph, with one parameter in X axis, and other parameter on Y axis. With equation allowing to get such function as on graph. I would suggest getting breadboard, https://en.wikipedia.org/wiki/Breadboard 760 pins unit cost me less than $2. With multimeter. The cheapest one $7. With range of various electronic elements to plug to breadboard. And battery. You should see on your own eyes what influence has plugging some element in circuit (in breadboard) on voltmeter, ammeter, wattmeter. How resistance changes with various resistors, how it changes with variable resistor while moving potentiometer. etc etc. Making LED light dimmer on breadboard would take less time than writing this post..

There is one way to stop this: education, high quality education. For free. Making museum-Noe ark with dinosaurs and telling people story that they lived together, it's exactly reverse direction, stupefying people...
