(I understand you) ...some people even commits suicides talking about honour... Brits committed sort of economical and political "suicide" by choosing to leave EU.. Now UK products will be less competitive on European markets. But they will still have to follow EU regulations to be accepted for sale on EU markets, without UK being able to have any inflence on these regulations.. Ain't plain stupid? If there would be referendum to jump off a cliff (this is what Brexit reminds me), would you still support it in second referendum again just to act honourfully? In Europe there was no serious war for over half century just because everybody integrated, assimilated, made friendships and families, made economical connections, living in peace, harmony and cooperation. And now you (UK) want to destroy all the effort put in making peace not war... Separated countries play to their own national goals.. We know whose influence divides us...

There is couple different types of supernovas. e.g. Supernova explosion can be result of collapse. Star's core runs out of fuel which can readily fuse. Iron atom cannot fuse with other iron atom at low temperatures as it is highly endothermic reaction. Therefor outer layers of star are no longer pushed away by particles created by core during regular fusion, and they collapse toward core. During this stage particles of outer layers accelerate to significant velocities gaining kinetic energy (prior explosion super giant star can have hundred millions kilometers diameter). When they hit core, or other particles from outer layers, explosion of supernova begins.. Do you agree with this? If you disagree, with this type of supernova, explain with details. Kepler's Supernova was in 1604. https://en.wikipedia.org/wiki/Kepler's_Supernova In 1572 there was supernova: https://en.wikipedia.org/wiki/SN_1572 In 1885 there was supernova in Andromeda galaxy. https://en.wikipedia.org/wiki/SN_1885A Wikipedia article of SN 1572 reveals origin of name of supernova. Tycho Brahe on stellar map and in his book called it "nova stella" (new star). https://en.wikipedia.org/wiki/De_nova_stella

Are you computer programmer? Physicists, astrophysicists, cosmologists are creating computer simulations of stars, galaxies, cluster of galaxies, to check whether their models match the real data. Did you make such simulation to check validity of your claims?

..it does not take into account possibility of mass extinction within these hundred years, or similar event, which would stop development of faster engines.. ps. Kinda similar "problem" to "why to buy computer/TV/mobile/electronic device/car today? Tomorrow/after week/month/year the same product will be cheaper and as good as today". It ends with endless loop, if there is constant progress.

Play with math is just a play with math (or numerology). One can even get constant result like in equation sin^2+cos^2=1. What is it? A sum of squared sine and sine with shifted phase (aka "cosine") waves.. or other example sin(x)+sin(x+pi)=0. Lack of electricity means that two sine waves cancelled each other due to different phases? Not really.. Variables used in physical equations, have physical meaning. If you believe that pulse DC has electrons moving in opposite direction, the answer is, no.

Nonsense. It results in pulsating direct current. https://en.wikipedia.org/wiki/Pulsed_DC Example of AC to DC transformation creates intermediate half-wave rectification. Full-wave rectification is still pulsing like we can see here (it is later smoothed by capacitor):

In code, or on piece of paper? Algorithm of conversion of any base-x system could be: (loop start) get modulo of number. push it on stack (FILO). divide number by the same base. (loop end) repeat until number is not 0. Then pop up elements ("digits") from stack and show to user after appropriate conversion (like elements with 16 > n >= 10 replace by 'a' to 'f' in the case of hexadecimal system).

Do you switch on a current? Then it is not DC. That is taught in first semester course material. But somehow you know more? Clearly not. Because you do not know how to learn. That wikipedia quote is missing many relevant facts. And demonstrates how easily one can be scammed. One who is an expert but forgot to first learn. Actually, I do have Van de Graaff generator in my apartment.. capable to create over 500,000 Volts.. In this 5 year old thread I showed how electrodes positioned at different angles influence where discharge will happen: https://www.scienceforums.net/topic/94255-electric-fields/ Properly would be to say that "accelerated electrons emit photons".. It is DC which we call pulsating direct current or pulsed DC. https://en.wikipedia.org/wiki/Pulsed_DC (anybody who ever created AC to DC rectifier should be familiar with this term) If we turn on Van de Graaff generator (or other electrostatic generator), it will continuously create discharge at rate which depends on distance between one electrode and opposite electrode. It is pulsating direct current. The shorter distance, the smaller delay between discharges. Small distance disallows device to fully charge, and it discharges after reaching enough breakdown voltage to pass electrons through medium. Air requires approximately ~30,000 V for each 1 cm distance between electrodes. It is typical breakdown voltage of air (it varies with pressure and temperature of gas). https://en.wikipedia.org/wiki/Electrical_breakdown Presence of radioactive material, or passage of cosmic ray particle, also influences (decreases) breakdown voltage. They ionize air/gas/medium, and electrons gathered at negative electrode easier find path to positive electrode. This feature has been used in many devices such as Geiger counter, Spark Chamber used by quantum physicists, and widely used smoke detectors using radioactive Americium-241. https://en.wikipedia.org/wiki/Smoke_detector#Ionization

"When a circuit is driven with direct current (DC), there is no distinction between impedance and resistance; the latter can be thought of as impedance with zero phase angle." https://en.m.wikipedia.org/wiki/Electrical_impedance Static electricity discharge is flow of electrons in just one direction.. Typical use of superconductor is to create powerful external magnetic field around it, impossible for traditional electromagnets (because of too large resistance of existing metals). So you need to use DC. Again.

What is molar mass (or atomic mass) of each compound in your equation? If you know mass of Hydrogen that escaped, you can calculate combined mass of LiH and NaH.

Correct. Why do you need to do it this way.. ? Reread 4th question once again and give full answer. Identify rules that have been violated .

What is the first rule that any chemistry teacher is teaching students about mixing acids and water.. ?

No. Almost. Pay better attention to numbers..

Well, they are margin of population. But being minority does mean that (mostly primitive uneducated) people should attack them and insult them.. They did not choose how their embryo developed.. I trust that doctors in hospital will notice that newly born baby and in later age patient has both male and female organs at the same time. But I don't think so doctors are prepared to such unusal situations and how they should adjust treatment of such patient.. starting from legal point of view: what to enter as gender in papers if there is no option for alternative than male/female (especially in on-line and/or computer forms)..

https://en.m.wikipedia.org/wiki/Hermaphrodite "Many fish change sex over the course of their lifespan, a phenomenon called sequential hermaphroditism. In clownfish, smaller fish are male, and the dominant and largest fish in a group becomes female." "For many species, sex is not determined by inherited traits, but instead by environmental factors experienced during development or later in life. Many reptiles have temperature-dependent sex determination: the temperature embryos experience during their development determines the sex of the organism." https://en.m.wikipedia.org/wiki/Sex

He is in superposition.. There is needed observer to set him up to certain state..

Numbers can be showed to human in decimal numeral system, as well as binary, hexadecimal or any else. It has nothing to do with SI units. Yes. It is easier to convert and calculate in modern numeral systems than e.g. imperial inches, feets and miles..

...because humans (at the moment) are using meters, seconds and kilograms etc. , i.e. International System Of Units (SI)... https://en.wikipedia.org/wiki/International_System_of_Units In normalized units c would be 1 [L/T]. In English imperial units system it would be completely different value. Conversion between different units systems require multiplication and/or division by the right coefficients. Building constructors use laser to measure distance. i.e. t=2d/c. Time of flight of laser beam to mirror and back after reflection is equal to double distance between laser and mirror, divided by speed of light (approximately, due to Index Of Refraction of air).

I did not hack you. If that is what you are imputing here. I do not have to hack anybody. Not the way you are thinking.

..he is drinking whisky as always on Friday night and weekend..

Unlike what some people believe, no, I am not one of LGBT community. I just sympathize with them, understanding and accepting their difference. On numerous occasions on this forum, I was even trying to explain how some of them were created the way they are.. ps. "Suing people" is definitely not the way I "work"..

In my country gender is encoded inside of personal identification number given at birth date. Is it not overt violation of rights of transgender person? What we can see on website: https://en.wikipedia.org/wiki/National_identification_number we have many countries which encode sex male, sex female, in their national identification numbers. Including ones which are quite open to gender minorities such as South Korea, Italy, Switzerland or Scotland. Norway just resigned in 2017 (so the all people born prior 2017 are still affected). Consequence of this, is that when somebody has transgender surgical operation, has to change national personal identification number.

...but there are apparent evidences of attacks of trolls and crackpots on this forum in this week... ps. "Attack of intelligence".. That would be something new!

Do you have experience linking to and using 3rd party external linkable libraries or using DLL in your C/C++ code? Do you have experience in using debugging tools in your IDE? Which C/C++ compiler and IDE are you using? Do you have experience in making subclasses of C++ class and overriding virtual methods, overloading operators etc. etc. ?

1) search net for ready linkable math libraries which allow arbitrary precision numbers. e.g. https://en.m.wikipedia.org/wiki/List_of_arbitrary-precision_arithmetic_software 2) make your own C++ class. Override math operators and implement needed functionality with required higher precision. Start from dummy class which is just using built-in double. Then add 3rd party lib functions or your own in implementation of operators. Did you overload operators? After exceeding fixed precision number there is overflow. Integer example: add 128 to 128 and it's 256. Too large to keep it in 8 bit unsigned char. In hex it is 0x100. Byte will have only the lowest bits i.e. 0x00 so you get 0 instead of 256. It is called overflow. https://en.m.wikipedia.org/wiki/Integer_overflow Such errors cause unpredictable behaviors of program. Use debugger to observe values assigned to variables in the real time, and you will see it on your own eyes.
