Hello! Does somebody performed experiment in which Chlorine gas has been separated to isotopes Chlorine-35 and Chlorine-37, and measured speed of sound independently per isotope.. ? Best Regards!

Kramer, do you even know what is black body radiation? http://en.wikipedia.org/wiki/Black-body_radiation

Earth receives energy approximately [math]1360 \frac{J}{s*m^2}[/math] (without counting loses caused by atmosphere). Distance 1 AU = 149,600,000,000 m Reversing inverse-square law gives energy emitted by Sun per second: [math] 1360 * 4 * \pi * 149600000000 ^2 = 3.825*10^{26} W[/math] (wiki mentions 3.846*10^26, so we're pretty close). Now if we will calculate energy at distance 40.4 AU = 6,043,840,000,000 m [math]\frac{3.825*10^{26}}{4*\pi*6,043,840,000,000^2}=0.833251642 \frac{W}{m^2}[/math] 5.2 W/m^2 is 2 * PI bigger than 0.8333 W/m^2.. 5.2 W/m^2 is at distance 16.16 AU from the Sun. Please also notice it's easy to make mistake by calculating distance satellite traveled from Earth 40.4 AU, instead of from the Sun (not saying it's in this case because I didn't verified data).

You're making assumption that every star has the same mass as Sun and/or that Sun's mass is average star mass across entire observable Universe.

How many water molecules is in [math]1 m^3[/math] volume? [math]1 m^3[/math] volume of water has mass [math]1000 kg = 10^6 g[/math] H2O has molar mass ~18 g/mol. [math]\frac{1,000,000g}{18\frac{g}{mol}}=55555.556 mol[/math] [math]1 mol = 6.022141*10^{23} molecules[/math] [math]55555.556 mol * 6.022141*10^{23}=3.34563389*10^{28}[/math] 1 Liter of gas has approximately 0.0446 mol = 2.686*10^22 molecules 1 m^3 volume has 1000 L, so 44.6 mol = 2.686*10^25 molecules (at normal pressure, room temperature) That's approximately 1245 times less than in water with the same volume. Only tiny tiny fraction of molecules of water has direct contact with molecules of air, on surface of water. Try to slice these volumes/areas to smaller and smaller pieces. 1m^3 volume with 1 m^2 area on top. Then 1mm^3 with 1mm^2 on top and so on so on, until you will receive single molecules at nano and pico scale. Air molecule don't let water molecule to fly away from container. If we will place glass of water in hermetic container, and pomp out whole air from it, nothing will be pressing at water from above, and water molecules will fly away from glass, becoming gas.

But electric field is result of presence or not presence of electrons, ions, or other charged particles, which are "real physical objects". There will be no electrons, or nucleus, there will be ~0 electric field around them. We use electric field to learn about other electric fields f.e. place plates of electrodes around flowing water, and causing change of direction of water (that's polar). We use magnetic field to learn about other magnetic fields f.e. place magnetized iron needle, and checking in which direction it's rotating. If there is lack of artificial magnetic field, it will rotate according to Earth's magnetic field. Magnet made of "real physical object" is source, and magnet made of "real physical object" needle is target.

Toilet-bathroom is good place to make experiments also. I have there couple 25L aquariums where is produced HCl, Hydrogen, Oxygen, and other substances (how many do you know people who are keeping their gold in toilet? electrodes...) So while watching how things are going (sometimes not going, 2 weeks ago there was explosion of Oxygen at 4 at night, so access to water is needed. I just finished repairing electronics that was damaged in this accident), I have new ideas how to improve setup, or ideas of new experiments, etc.

I have always 40+ empty pages of paper A4, and calculator in my toilet. Used every day not once..

Typical house in EU has power provided U=230 V,I=18 A, P=U*I=230 V*18 A = 4140 W = 4 kW After exceeding Imax fuses are disconnecting.. Better check your maximums before proceeding (even if you're in factory).

C'mon! Then it's not true. Atom is nucleus + electrons. You would have to say "real physical object is made of nucleus/baryons", to reject electrons from being real physical objects. But we're made of electrons that were created (or at least could be) in pair production, while its antiparticle travel somewhere else, or annihilated already..

Didn't I say in #13 post about pair production? [math]\gamma + 1.022 MeV \rightarrow e^+ + e^-[/math] [math]\gamma + 1.876544 GeV \rightarrow p^+ + p^-[/math]

If particle is not "real physical object", then we (clusters of billions of billions particles) are not real either.. Are you suggesting Universe is simulation? It could be. But if it's perfect simulation, then we will never be able to find it out. Suppose so, intelligent life is appearing in the Universe. It's evolving. Learning physics. Creating computers. Making simulation algorithm that has everything included. And in simulation there is happening Big Bang, then stars are forming. They're fusing etc. etc. and finally after billions years of simulation there is appearing intelligent simulated life, and cycle is repeating..

If photon is not real then electron, positron nor any other particle is not real physical object either. Photon can create pair of electron and positron, or any other pair of more massive particle-antiparticle... So, if electron-positron are real physical objects, then photon that created them must be as well real physical object.

Unit of pressure is [math]\frac{N}{m^2}=\frac{kg*m}{s^2*m^2}=\frac{kg}{s^2*m}[/math]

Do you need to use spectroscopy to figure out substance? Or do you just need to figure it out any way possible? Looking at http://en.wikipedia.org/wiki/C8H9NO2 They seem to have significant difference in properties, like melting/boiling points.. Another way that came to my mind is to do spectroscopy of all these known substances from list of possibilities, and compare with what you have unknown.

They don't want you to remove their software. Typical problem... Brute force method is simply find folder and delete it. But this way you won't have registers updated and appropriate Documents & Settings removed. You should probably ask on Sun's support forum. Maybe in newer version they fixed issue.

For $200 you can get pure non-touchable monitor 24" LED... If you wouldn't have money issue, I would suggest Wacom Cintiq Wacom Cintiq 13" HD have not bad price $1000 https://store.wacom.com/us/en/product/DTK1300/ Of course better is 24" version, but also much more expensive: https://store.wacom.com/us/en/product/DTH2400/

Significant quantity of similar charges is easily visible: Not charged (neutral): Do you see on the streets people walking with hairs pointing each one in different direction (other than punks)?

When we're sending command to distant satellite like Voyager, it's arriving after some time [math]t=\frac{d}{c}[/math] (d - distance). And satellite is returning result after yet another time t, giving total delay between sending and receiving answer 2*t. Astronauts that landed on the Moon had delay 2*1.21=2.42 to 2*1.35=2.7 seconds. When speaker talked with them, their answers were arriving with such delay.

Press ctrl-alt-del and check out in Task Manager how much memory is consumed during playing video.. On WinXP after booting system and opening Firefox and starting browsing net (3 tabs) memory usage is already 987 MB = ~1 GB almost.

Correct. My new application for chemistry is also showing it's good answer, see:

Which companies ordered, received eCat, and are using it right now for energy production.. ?

It's not PHOTO. It's 3D computer rendering visualization....

Actually it's not me, but my applications that I wrote.. I am just entering data to applications showing fusion and decay energy calculations, and they're showing result for me (and copy'n'paste to posts)..
