In physics you’ve four fundamental forces and 4 fundamental dimensions and 2 fundamental kinds of stuff with connected qualities and fates. In every situation you’ve something, the odd one out – the one which isn’t symmetrical – the jokers within the physics deck. What exactly are they?
1) You’ve four fundamental forces which three have symmetry.
*Electromagnetism or even the Electromagnetic Pressure where symmetry abounds – magnetism can generate electricity electricity can generate magnetism. Electricity/magnetism symmetry includes the positive versus. the negative the northern pole versus. the southern pole of the magnet attraction versus. repulsion the negative electron versus. the antimatter twin, the positron.
*Strong Nuclear Pressure has symmetry for the reason that inside the nucleus of the atom, positively billed protons repel one another – protons push outwards, yet gluons have them within their assigned place inside the nucleus – gluons pull inwards: attraction versus. repulsion. anti-thermo.
*Weak Nuclear Pressure has symmetry for the reason that particle interactions will go either in direction. Weak interactions govern radioactivity. Radioactive nuclei can clearly be produced additionally they clearly may come apart in the seams (radioactive decay)!
*Gravity (the Joker): Gravity is unidirectional – it’s attractive only. There’s no equal and opposite antigravity with the exception of the minds of sci-fi authors.
2) You will find four fundamental dimensions (ignoring unverified string theory) which three have symmetry.
You’ll need all dimensions (space-time) to be able to specify any particular event. You can’t possess a happening wide without also getting it take place in time you can’t come with an event that occurs over time without them also happening inside a 3d space. Yet only three of those dimension is symmetrical.
*Left & Right is clearly symmetrical. These movements could be un-tied or reversed.
*Back & Forth can also be clearly symmetrical. These movements could be un-tied or reversed.
*Up and Lower are a couple of directions which are clearly symmetrical. These movements could be un-tied or reversed.
*Time (the Joker): Time is unidirectional. Time flows one way only, from past to provide to future. There’s no equal and opposite arrow of your time that extends in the future to the current and to the past. Time can’t be un-tied or reversed. You can’t go back in its history and alter what’s already happened. You recall the past you don’t recall the future.
3) There’s two types of stuff as well as the qualities of stuff (like velocity, temperature, pressure and density) and also the ultimate fate of stuff.
*Mass: There is a conservation law – the conservation of mass/matter – which claims that matter can neither be produced not destroyed, only altered healthy. Matter (mass) could be transformed into other kinds of matter. You are able to move from a good to some liquid to some gas and again. You are able to move from hydrogen and oxygen to water and from water to hydrogen and oxygen. You are able to fuse hydrogen into helium (which forces the sun’s rays) also is a good example of the equivalence between matter and (see below) since that fusion process releases lots of energy at the fee for a small little bit of mass. Matter (mass) also offers another type of symmetry – antimatter. Antimatter is equivalent to matter just with opposite electric charge (such as the negatively billed electron and it is antimatter counterpart, the positively billed positron).
*Energy: There’s another conservation law – the conservation of one’s – which claims that energy can neither be produced nor destroyed, only altered healthy. Energy could be transformed into other kinds of one’s. Caffeine energy natural in gas will get transformed into the kinetic energy of movement as well as heat energy. The electromagnetic heat and lightweight the sun’s energy forces up eco-friendly plants, which convert that solar radiation to chemical energy and eventually your gas like a fossil fuel, or fuel you directly while you munch in your salad.. Unlike matter however, there’s no anti-energy since energy does not have charge. However I hear an objection here. How about electrical power? Surely electricity may be the flow of electrons and electrons have negative charge.
