Sensei

I am not sure why it's in politics.. The main problem is that doctors demand money for healing patients. They are thinking about it BEFORE they even get to medical university! They want to be "well paid" and quickly rich. Medic should not be just a job, to earn money, or (in current western standards) "a lot of money" (> $100k ?!? Insane!). It's kinda like wanting to be a priest because people will give money 'on a tray'... Nobody who wants/demands money should become medic or priest! Only people who truly wants to help other people should become medic. Without any money behind this. Who demands money for saving somebody life demands full condemnation! There is nearly not a week here without some scandal about "ambulance not send" to somebody who called for help, but because his/her injures/state was not health dangerous (by judge of call), and he/she died. All because of money. Ambulance management not let ambulance to go, to save money for possibly false alarm, that later it appeared to be true alarm.. All because of money! Ambulance stations should not be private businesses aimed at earning money.. ! Hospitals should not be private businesses aimed at earning money.. ! Outpatient clinics not be private businesses aimed at earning money.. ! If government has to pay every month pension/retirement we have obvious conflict of interest with government paid medics - if patient lives longer, government has to pay him/her more money, if he/she lives a lot longer, he/she will get more money than he/she paid in the past. So from government financial point of view, patient that pays for medical care whole life, and then after retirement dies as soon as possible is the best "client". All because of money! We have queues long for several years reservations to free doctor, that you would rather die than to live to see him.. At the end who has more than 50 usd (typical 1h price per visit) is going private (10% of minimum gov income per month for visit, so such doctor will earn 100% of minimum gov income in single 10h day! And up to 20-30 times more than regular people per month) Retired people (without money) (usually who need doctor the most) have to wait several years for visit at specialist. To get to specialist you need to get referral from general doctor. So actually you need to meet two doctors one and then another, even if you know what kind of disease you have. Even if you met 2nd doctor multiple times.

In application I have functions: double get_isotope_mass( int protons, int neutrons ); // read isotope database and return mass in units double get_isotope_energy( int protons, int neutrons ); // call above, multiply by 931.494 MeV etc. return energy in [eV] double get_nucleus_energy( int protons, int neutrons ); // call above, and subtract electrons energy (protons * 0.5109989). return energy in [eV] All other code is only using get_nucleus_energy(). I wrote application, to not have to worry about calcs. Simply enter protons,neutrons quantity and app is displaying what are possible decay modes and Decay Energy. For instance decay of Plutonium-239 is prohibited in all modes but alpha decay, alpha decay energy 5.24454 MeV does match article http://en.wikipedia.org/wiki/Plutonium-239

Not only. Proton emission also, double proton emission. It's easy to make mistake that will remain unnoticed if we will be doing such shortcuts. (in above example one electron and one proton will be free)

I don't know about what book you're talking about. Certainly I didn't read it. I think so it's too late. If discussion will be progressing mods will split it to other thread. I see no problem. So, what is explanation of refractive index in your country.. ?

Refractive Indexes are measured for specific wavelength/frequency of laser (or light in old times). Especially in gases it's even worser- there has to be taken into account also temperature and pressure. On wikipedia RI article there is also mentioned that RI changes with density of glass. For instance we have data RI=1.33 for f.e. 532 nm, RI=1.34 for f.e. 650 nm, RI=1.32 for f.e. 405 nm, then RI is obviously not constant. Different value of RI for different light wavelength/frequency. You said "Refraction is only a problem if the index isn't constant," And I am asking which material fulfills your RI constancy for lights with as largest range of frequencies as possible (preferably not just visible spectrum).. ?

Which material has uniform refraction index in f.e. frequencies from 1 Hz to Compton Frequency?

Do you know how to calculate Decay Energy of unstable radioactive isotope? First, find parent isotope mass. They're in f.e. wikipedia articles such as http://en.wikipedia.org/wiki/Isotopes_of_hydrogen (last portion of link is name of element). For instance Carbon-14 has 14.0032419894 u Then, you need to multiply it by 1u = 931.494 MeV to receive total energy of nucleus + electrons. Then you need to get rid of mass-energy of electrons. Multiplying 0.510999 MeV by quantity of protons/electrons. Subtract total energy of electrons from energy of isotope. Repeat it for daughter isotope. In Carbon-14 case it's Nitrogen-14. Subtract N-14 nucleus energy from C-14 nucleus energy. Subtract electron energy (it's emitted during decay together with antineutrino) Result will be Decay Energy of isotope (kinetic energy of particles + energy of neutrino in our case). Decay Energy must be positive value. If you will calculate Decay Energy from stable isotope such as Deuterium, Helium-3, Helium-4 for all possible decay modes you will see that D.E. would be negative value. Thus these particles are stable. For Carbon-14 it's 0.156 MeV. As you can see this value does match article: http://en.wikipedia.org/wiki/Carbon-14 Other examples: Fusion of proton-proton, decay of carbon-11 and decay of Mangan-54: I wrote computer application which has built-in database of isotopes and calculates possible decay modes and released energy.

Deepak Kapur, do you saw Newton's cradle? http://en.wikipedia.org/wiki/Newton's_cradle It costs less than $10 in western countries, and allows visualizing conservation of momentum (while interaction) between objects with the same mass, or conservation of momentum between objects with different masses, etc. etc.

Actually both wood and iron are made of protons, neutrons and electrons. Simply their configurations are different. There is no two pieces of irons with equal structure (due to f.e. contamination). and there is no two pieces of woods with equal structure. They are just more or less similar, but never equal. Like finger prints. First of all, you should start from analysis of what acceleration and velocity is. Velocity is change of position of measured object over time. f.e. we measure object to be at locations: at t=0 x=0 at t=1 x=10 at t=2 x=20 at t=3 x=30 We can subtract locations of object at different times x(t1)-x(t0) to receive distance object traveled (in meters). If we will then divide it by t1-t0 (in seconds), we will receive velocity (in meters per seconds). v=(x(t1)-x(t0))/(t1-t0) so position of object at time t is x(t)=x(0)+v*t = x(t0) + (x(t1)-x(t0))/(t1-t0) * t Velocity is constant in this example. Thus acceleration is 0, and force is 0. Acceleration can be calculated by taking two velocities at two different times: Imagine measured data: t=0 v=0 t=1 v=1 t=2 v=2 t=3 v=3 Velocity is increasing over time. Acceleration is a=(v(t1)-v(t0))/(t1-t0) Velocities in meters/seconds divided by seconds, gives acceleration in meters/seconds^2. If v(t1) is equal to v(t0), velocity is constant, and we have no acceleration. Force in Newtons is mass in kilograms multiplied by acceleration in meters per seconds^2. Momentum is p=m*v [kg*m/s] So force will be also F=(p(t1)-p(t0))/(t1-t0) Change of momentum over time.

You are bored by knowledge. Apparently you're on wrong forum. Try TMZ.com or so..

You want to make theory of everything, and you don't even know what is ionization energy... what does mean spectral line... etc. etc.

C10H15NO is formula of many different substances: http://en.wikipedia.org/wiki/C10H15NO

Megatons of what? Big Bang was not explosion. What we call explosion on Earth is release of energy stored in chemical bonds and production of oxides in large quantity that are accelerated to high velocities.

Sensei means teacher in Japanese. Read links that I gave you above. It will enlighten you a bit.

No. You first have to learn physics. When you will know everything what typical student knows after several years of education, then it's time for your own hypothesis.

We can speak only how strong or weak is weak force in comparison to other forces, electrostatic, magnetic and gravitation. Big Bang is not force. More info about electrostatic force will provide Coulomb's Law http://en.wikipedia.org/wiki/Coulomb%27s_law Weak force is not uniform in the all particles. Some particles are stable (example is proton/antiproton and electron/positron), some other are theorized to be stable because nobody detected them to decay (Deuterium, Helium-3, Helium-4 f.e.), and some others are unstable. None chemical element has all isotopes stable. These unstable particles have measured half-life time. Imagine 1000 unstable particles at time t0 after half-life time (t0 + half-life) we have 500 particles, after another half-life time (t0 + half-life + half-life ) we have 250 particles, and so on, so on. Half-life article to read if you have not already http://en.wikipedia.org/wiki/Half-life Radioactive decay article to read http://en.wikipedia.org/wiki/Radioactive_decay Isotope article to read: http://en.wikipedia.org/wiki/Isotope Radioactive decays of chemical elements we can split to couple common methods: The most popular is beta decay minus and beta decay plus. Beta decay minus is emitting electron and antineutrino, Beta decay plus is emitting positron and neutrino. http://en.wikipedia.org/wiki/Beta_decay Another one is proton emission: http://en.wikipedia.org/wiki/Proton_emission and neutron emission: http://en.wikipedia.org/wiki/Neutron_emission Heavier elements decay model is alpha decay http://en.wikipedia.org/wiki/Alpha_decay More exotic decay is double beta decay http://en.wikipedia.org/wiki/Double_beta_decay and gamma emission http://en.wikipedia.org/wiki/Gamma_ray Other modes are described in radioactive decay article.

That's already done.

anonymousone, you should be at stage of asking questions about physics. Not creating your own pet theories. You're behaving like your would never attend to primary school, not to mention high, and studies. It's unbelievable to mix all units and don't understanding what is dimensional analysis, how to convert units etc. etc. That's primary school knowledge here. Ask question in separate thread, and it'll be answered, if it's well established knowledge. f.e. "how to calculate decay energy?" f.e. "how do we know that proton has 938 MeV energy?" etc. etc. Anything that you obviously don't know..

Not sure what do you meant. But on graph you showed acceleration. At t=0 v=0.0 m/s At t=1 v=0.5 m/s At t=2 v=1 m/s 2D vector needs 2 components. 3D vector needs 3 components. and so on, with higher dimensions. Scalar velocity is equal to: sqrt(x^2 + y^2) for 2D vector sqrt(x^2 + y^2 + z^2) for 3D vector and so on, with higher dimensions.

You're talking about obvious, must have, things that should be done with the all data coming from $_GET/$_POST/$_COOKIE etc. (not just session id). Checking IP is not replacement for basic checks, but yet another level of security. All mine Internet bank accounts, and stock market brokers that I am using, are utilizing this technique. You cannot be logged to the same account from two different computers at the same time. Good secured services refuse it immediately. They ask you "you're logged from IP x.x.x.x, do you want to terminate session and open new one?".. Even better is making history of logging with IP recorded. And showing this info to user when he/she is starting session. User will be immediately warned about logging somebody with "wrong" IP, at wrong date and time.

Do you meant 250 thousands or 250? I can't believe in second without serious issue in program.. I am often programming particles, and putting them to octree/kd-tree is obvious standard procedure of speeding them up.. If you "forgot" to turn Floating Point Model: Fast, instead of default Precise, this also can cause several hundred percent slowdown.

Session id stored in cookie should be id to database entry in currently open session table. Database record should store IP address of owner of session, and code should check whether db IP matches with what is clients IP. This will make sure that even if somebody intercept cookie value, he/she won't be able to use it, because their IP will be different than original client that opened session. As long as they didn't intercept whole client network and are able to show up as the same IP..

Cubic lightyears? Light year is not unit. Do you meant m^3 * s^-3? or m^3 (simply volume)? Do you really meant "x = ed = f" Before editing there was "x*e*d=f" Either way, units don't match between sides of equation.. How can you say that energy x in Joules is equal to force f in Newtons.. ?

Energy has unit Joules [J], or electronVolts [eV]. How can you add it to variable that has unit Newtons [N]?

But quantity of particles is unitless, isn't?
