I see it's yours video. So how about making couple tests? f.e. instead of using permanent magnet, use electromagnet and variable resistor to control amount of current flowing through coil. The higher current, the stronger electromagnet. Then change polarization by swapping + and - in DC. How about using small frequency AC for electromagnet (current will be flowing once in one direction, then in other, and it'll be changing polarization of electromagnet). How about using wire through which current is flowing and surrounding container with ferrofluid.. ? So it'll be kinda like core in electromagnet. Did you try if your fluid is passing current.. ?

It has error, page 7 "For Plank's constant h, the accepted value is 6.626×10−39 J·s" It should be -34

Ridiculous. It must have Planck constant. As it would ruin plentiful in either classic and quantum physics. If you have light source which is emitting uniform wavelength photons with power P from point source, in the all directions (inverse-square law). Single photon has energy: E=h*f or E=h*c/wavelength Power P [W] is E/t, energy by time. If you sum all photons energies, multiply h*f by their quantity, you will receive total energy emitted in time unit. Etotal = h*c/wavelength * quantity of photons Inverse-square law E=Etotal/(4*PI*r^2) so finally: E=h*c/wavelength * quantity / (4*PI*r^2) These photons deliver energy from source to our detector. f.e. Sun is heating Earth by photons. If you would replace h*f by some other value than 6.62607*10^-34 J*s * frequency, energy received in Joules would be different. Which would be easily detectable as different temperature. Actually that's how it has been detected that different wavelength photons have different energies, by splitting white light on prism, and then heating few samples of water (for red, green, blue light) and reading temperature increase.

I didn't want to give final code, as it sounds quite like homework.. Why do you want to use regular expressions for such silly task as checking whether 1st character is digit or not.. ? Equivalent of C/C++ code: if( !( ( row[ 0 ] >= '0' ) && ( row[ 0 ] <= '9' ) ) ) or if( !isdigit( row[ 0 ] ) ) will be sufficient (and faster, reg expressions are pretty slow). (assuming null-terminated row is in buffer) http://www.tutorialspoint.com/python/string_isdigit.htm

Open file, read row by row counting lines. If line counter is at specific line, return it. Then close file handle.

Isotope is stable when there is not allowed decay mode to other isotope with smaller mass-energy. That's it, if decay would violate one or more conservation, decay is not allowed. The most important is conservation of energy. Deuterium is not decaying to free proton and free neutron, because there is missing 2.22 MeV energy. When this energy is delivered from external source (such as alpha particle with kinetic energy higher than 2.22 MeV), Deuterium can disintegrate. And it's used as source of free neutrons in other experiments for instance.

Units mixed with symbols? Capacitance is in Farads F. Charge Q is in Coulombs C. Voltage U is in Volts V. Current I is in Amperes A. 1 F = 1 C / 1 V 1 V = 1 A * 1 ohm Substitute: 1 F = 1 C / ( 1 A * 1 ohm ) But we know that I=Q/t, or Q=I*t. In units it'll be 1 C = 1 A * 1s. so 1 F = 1 A * 1s / ( 1 A * 1 ohm ) = s/ohm

Acceleration of initial accretion disk https://en.wikipedia.org/wiki/Accretion_disc. Yes. f.e. direct collision with other cosmic object, resulting in rapid deceleration, or changing path (and vaporization of the all living organisms on the Earth). It happens all the time but with small objects in f.e. kuiper belt. f.e. indirect passing through massive cosmic object in close region of Solar System. See thread about hypervelocity stars http://www.scienceforums.net/topic/90600-hypervelocity-stars-new-mechanisms-of-creation/ This is pretty similar case, but with stars and black hole. Cosmic object can be ejected from its normal path (better fate than being suck by black hole).

You also mentioned "quarks and leptons", in the same line as "wormholes". Their decay is what is running nuclear plants, so far using U-235. There can be other unstable/stable isotopes which can be turned to fuel of future. Scientists have to analyze newly produced unstable isotopes to check whether they could be used as fuel of future. Nuclear spin of theoretically unstable isotope can cause it to be metastable because there is not allowed decay mode (or time is significantly increased). f.e. what should decay quickly, is delayed, and decaying from excited state to ground state, by emitting gamma rays, much longer than expected. Don't you think so fluorescence is interesting subject to discover by scientists? Read about using Tritium as source of electrons that excite other atoms https://en.wikipedia.org/wiki/Tritium_illumination to emit light in Wristwatch clock.

You're mixing units. Time is in seconds, Length is in meters, Energy is in Joules, which is kg*m^2/s^2 Mass is in kg. You cannot add two or more variables/const with different units.

g is varying even from place to place on Earth. https://en.wikipedia.org/wiki/Gravity_of_Earth g vary as a function of latitude. That's it, it depends on distance to Earth's center. But if it does so with Earth, it must also does with Sun, and Moon, and Milky Way center. Once we're the closest to the Sun at noon, and the furthest from the Sun at midnight. ps. I would start analyze from checking in what exactly days of year were G calculated in the past (function of distance to Milky Way center).. ps2. Variation of g is used during exploration of resources https://en.wikipedia.org/wiki/Gravity_gradiometry

Yes, I know. But remember we're talking to non-scientist. If you want to be so much precise, then give him amount of introduced error: "In March 2015 the NIST-F2 caesium fountain clock reported a uB of 1.5 × 10−16. At this frequency uncertainty, the NIST-F2 is expected to neither gain nor lose a second in more than 211 million (211 × 106) years." (from https://en.wikipedia.org/wiki/Atomic_clock )

Quantity of decays is dropping exponentially, as quantity of unstable particles is gone. ps. You can learn how to calculate decay energy reading article in my signature. There is also graph with decays per second as function of time, OpenOffice SpreadSheet project to download: http://www.scienceforums.net/topic/83245-a-question-on-radioactive-decay/?p=806204

I have Android 5.0, so maybe it's version dependent.

I have Samsung Galaxy S5. Assume you have Android (you didn't mention which version, every one is different) tablet. When I click on Applications > Settings, near bottom of the list, there is Internet icon. In Advanced, there is option "content settings" (don't know what it's called in English version of phone). Once you click it, there is "Default memory for writing". I have picked up "Device". Are you able to switch it to card.. ? I have built-in 16 GB, and didn't reach level of usage needing plugging card, but I guess so when there is card plugged, this option will change target for downloads..

Are you aware of Hafele–Keating experiment? https://en.wikipedia.org/wiki/Hafele%E2%80%93Keating_experiment If they're both at rest, in same FoR, clocks are synchronized.

You don't have fire.. ? If there is substantial amount of gas then place above it up side down beaker, filled with water first, so it'll be filled by gas going up. Then try to fire it. If there is explosion, it's Hydrogen, the most likely. In presence of not flamable gas, such as Carbon dioxide, fire will shut down. In presence of Oxygen, fire will start burning more intense. How about placing it in other liquid, that has no water.. ? If it's caused by reaction with water, there will be no gas, or reaction will be different. If it's what John said, gas bubbles will appear also.

Special relativity is used all the time in quantum physics. During f.e. calculations of decays of unstable isotopes, calculation of particle collisions in particle accelerators in CERN etc. If you have high resistance, your current (and thus strength of created magnetic field) will be very small.. I=U/R for U=12 V, R = 100 ohm, I = 0.12 A, which means Q=0.12 C in second, which means 7.4898*10^17 electrons per second. Coils are typically made of Copper, because it has very small resistance! To be able to pass as large current as possible. To have as large magnetic field as possible. for U=12 V, R = 0.1 ohm, I = 120 A, which means Q=120 C in second, which means 7.4898*10^20 electrons per second. Scientists at CERN, while using superconducting electromagnets have to fight with what you described, as it can cause serious damage to devices. Once the main source of power is turned off, and coil is starting making its own current, there should be secondary circuit turned on, with elements that have high resistance, such as lightbulbs, or heating elements in water/oil, that will convert stored energy to photons in visible range, or heat, that will be easily to cool down.

Hello! I see subject hypervelocity stars is not very common here. Just a few threads about it, years ago. So if you're not familiar with them please read first http://www.space.com/24432-hypervelocity-stars-ejected-from-milky-way.html http://www.space.com/8801-superfast-star-shot-milky.html Quote from article: "None of these hypervelocity stars come from the center, which implies there is an unexpected new class of hypervelocity star — one with a different ejection mechanism." I would like to share my hypothesis how this could happen (at least for some of them): Hypervelocity star (or two not joined together yet, but accelerated normal stars), ejected from center of galaxy, hit yet another star on their path, and joined together with it. Because of having to conserve momentum, it appears coming from different location than center of galaxy.. So precise analyze of path in the past of these stars will tell where they approximately hit something, using typical velocities at given radius from center of galaxy. Best Regards!

You discredited yourself, before you even started explaining your experiment (that you're just mentioning).. So, I guess so, it's all "valid" as the rest of your claims.. I will give you something for consideration. Classically current I, voltage U, charge Q, are not quantized. But in oil drop experiment we were able to find out quantization of charge e = 1.602176565*10^-19 C. https://en.wikipedia.org/wiki/Oil_drop_experiment Equations for power P = I * U and for energy (simply power * time): E = I*t * U = Q * U Q is quantized in chunks 1e, 2e, 3e, ...., 10^18 e and so on. There can be 1 electron, 2 electrons, or billion electrons, but not half electron. Kinetic energy of single electron in wire in your radiowave emitting device: E.K. = 1e * U That's what electron could release at maximum upon acting with matter. Typically heating it. But can also emit visible light (like it happens in LED, lightbulb, laser). If source electrons in battery (or other source of electric power) flowing through wire, through your radiowave emitting element, were quantized, how come emitted by them photons won't be quantized either.. ? You are concentrating on detection of RF, instead of also looking at source of energy that you're using to producing your RF photons.

Induction in non-metals? How do you explain bouncing off radiowave from walls in your room in that case? They're made of non-metals (or metals bound in compounds such as white paint Zinc Oxide or Titanium Oxide).

You can/should do this experiment by yourself. PMT cost $30-$40 http://www.ebay.com/bhp/photomultiplier

What is wrong with avalanche mode? Single photon, no matter if it's RF, visible, or x-ray, has very little energy, in comparison to everyday macroscopic scale.. So there is needed amplification. You could miss annihilation of matter with antimatter if you would use just your own eyes (or your devices). It's 400 millions times less energy than battery with U=5 V, I=25 mA, t=1s.

Knowledge of somebody is increasing with time (unless he/she has Alzheimer or lost memory), so you could show relation f(x)=knowledge(time)=knowledge(time-1)+average knowledge gain per second*1s (if time is in seconds unit). Knowledge second ago is smaller than knowledge now. New data arrived to your brain by input devices such as eyes, ears, touch, smell etc. They were collected in your brain. Could remain there for seconds, hours, days, or years. Depending on importance, and their value, and whether you will be repeating/remembering them. But the problem is they don't increase in regular steps.. One day you learn more, other day less. I thought so it's more mathematical question, than physics.
