Each atom, each isotope, even if it's otherwise perfectly stable, has different energy required to destroy nucleus. There can be human induced destruction of nucleus by adding this "missing energy". It's called induced radioactivity/artificial radioactivity. https://en.wikipedia.org/wiki/Induced_radioactivity Electron after event will be ejected, no longer electrostatically attracted by nucleus.

Very sad photo:

The result of this action, will be that everything produced by USA which uses steel and aluminium will be more expensive in either internal American market and for export to world. Costs of Boeing, and other airplane building companies, shipyards and shipbuilders will grow. Produced by them goods for export will be less attractive to buy for world customer. If you have stock market account, you can bet on short-selling companies listed here: https://en.wikipedia.org/wiki/List_of_shipbuilders_and_shipyards

There is plentiful evil, greedy priests which do it just for gold, money, power and prestige..

Let's me put in Lady Gaga performance of John Lennon's Imagine: https://www.youtube.com/watch?v=q3ues1stefk "Imagine there's no heaven It's easy if you try No hell below us Above us only sky Imagine all the people living for today Imagine there's no countries It isn't hard to do Nothing to kill or die for And no religion too Imagine all the people living life in peace, you You may say I'm a dreamer But I'm not the only one I hope some day you'll join us And the world will be as one Imagine no possessions I wonder if you can No need for greed or hunger A brotherhood of man Imagine all the people sharing all the world, you You may say I'm a dreamer But I'm not the only one I hope some day you'll join us And the world will be as one"

Radioactive Carbon C-14 can be made after bombarding stable Nitrogen N-14 in air by free neutron in reaction, e.g.: [math]_7^{14}N + n^0 \rightarrow _6^{14}C + p^+[/math] Free neutron is made in reaction caused by cosmic-ray particles (mostly relativistic accelerated particles from the Sun) e.g. [math]p^+ + p^+ \rightarrow p^+ + \pi^+ + n^0[/math] Free neutron has to have enough kinetic energy to cause this reaction. Slow thermal neutron will not knock free proton away.

To estimate amount of gas, you will need to know pressure and temperature inside of container, and exact volume of container. And rearrange gas law equation. e.g. if you will buy 5L of gas in hermetic container, use a bit of it e.g. 1L, then you still have 5L of it, but at lower pressure than previously.

Very good ideas hypervalent_iodine. How about algae development in couple containers, each one with different concentration of agricultural wastewater (and test effect of various fertilizers on their growth). But you didn't tell us in which area of science.. Chemistry? Physics? Biology? In projects mentioned by hypervalent_iodine, things must go wrong with some plants, as they receive something (e.g. salt) which kills some of them.. If you will be doing such long time going project (for days or weeks), place at fixed position camera which will record timelapse, and generate video from separate photos. You will have something to show on YouTube in science section.

Don't "buy Hydrogen" (where?).. Do electrolysis of water..

Any references.. ?

You omitted essential parameter. Temperature of water. If you eat ice cream, or ice, it has <0 C, human body has to spend energy to unfreeze it and increase to ambient temperature of body. If you drink 50 C hot tea. That energy in hot drink does not disappear. Remains in your body, increasing temperature of your body. Does water has food calorie? No it doesn't have food calorie. Does hot water has energy? Yet it does. 4.1855 [J/K*g] * mass_of_water [g] * ( T_of_water - T_of_your_body ) [K]

OP nowhere said he is interested in just "food calorie". He said about "calorie". We're in science part of forum, so I am interpreting it as "calorie = (historical) unit of energy".

While burning Water and carbon dioxide gases are results of burning material to check its caloric (food) value. But energy released during this reaction is in e.g. kinetic energy of newly created molecules. Liquid water particles at 100 C has higher e.g. kinetic energy than water at 20 C, or 36.6 C. During collision with "colder" molecule, kinetic energy is partially or fully transferred to it (elastic/inelastic scattering)

Calories that can be used by human body, depends on difference between temperature of drink and temperature of your body. 4.1855 J/K*g * mass_of_water * ( temperature_of_water - 36.6 ) = energy that you can gain because of drinking just water. But typical e.g. hot tea has no more than 40-50 C, so put inputs in equation, and you have 4.1855 * 250 g * (50-36.6) = 14 kJ of energy. 1 calorie = energy needed to increase temperature of 1 gram of water by 1 degree. From definition of calorie. https://en.wikipedia.org/wiki/Calorie

How about "Web Editor"? https://creativepool.com/articles/jobdescriptions/web-editor-and-web-author-job-description "A web author/editor is responsible for the content and images used on a website.

To be honest, in Europe, it would not happen, as police officers here are learned to shoot at legs first.. (if there would be even reasons to do it in the first place!) In US, police officers are like in some permanent madness state.. ("shoot first, then ask for ID!") (Current) US government does not help with anti-immigrant sentences.. There is very easy to get rid of such unbelievably ridiculous cases as Philando Castile. Simply give every single US police officer camera which must record everything what they do all day long...

Not shocking at all. Older people often have problems with eyes..

Hm.. I don't agree with this statement.. You're trying to use mathematics, to classify human-made concepts like "morality".. What is this "morality"? What is this "greater moral" or "less moral".. ? If you will kill bug, are you more moral than if you will kill fish? If you will kill fish, are you more moral than if you will kill cow? How to judge it.. ? What if that fish, or bug, was new specie which (if you wouldn't kill it) evolve to completely new branch of organisms, which would after millions of years become intelligent, create civilization, and start flying to cosmos.. basically replacing humans after e.g. nuclear war.. ? How to convert it (human-made concepts like "morality") to math number (integer? real? irrational?), so you will be able to use comparison operator on them.. ? One of my beloved examples: mass extinction of dinosaurs. From point of view of dinosaurs, it was the end of their life.. the worst est day in their entire history.. From point of view of mammals (at least the one which survived), the greatest thing that could happen. Now, some humanist-religious person would say "thanks God, that dinosaurs died! He/she did it for us to be able to appear on the Earth!".. and it'll be example of anthropocentrism, misconception which is the core of the all major religions of this world, that Earth was made for humans, and source of many modern problems, with e.g. global warming, destruction and devastation of natural environment, etc. etc. The same might say successor of fish, or bug, after millions years from now.. "thanks God, that humans died! He/she did it for us to be able to appear on the Earth!"..

I was answering from programmer's point of view, about possibility of implementing the feature, without saying it should be done, or should not be done. The easiest would be of course write feature request to authors of software. Additionally to exclusion of some sections from voting system, there could be added weighting system e.g. each section vote can have different value to overall ranking. Default is 1:1. But we would like to decrease weight of vote in e.g. jokes section for sure.

Not necessarily actually, if somebody would really really need it. We can generate to temporary buffer (if somebody used e.g. scrambled/obfuscated code) , instead of directly to stdio, and then analyze that buffer, to remove what is not needed. In PHP it's done using ob_ (...) functions: http://php.net/manual/en/ref.outcontrol.php

From programming point of view, it would take few minutes to implement: Pseudo-code: if( get_section( $section_id ) != "Politics" ) { add_vote_up_down(); } In other words, if user is in section different than Politics, buttons for voting are generated and sent to forum user. ps. If you want forum developers to implement feature that you need, you just need to send feature-request to them. Without feature-request they have no idea what is needed, and they do what they want by them self.
