THE WEAK FORCE, MIGHTY MOUSE OF PHYSICS?

All is made of energy conservation, all except perhaps gravity which may be a source of perpetual motion to continually wind up the cosmos, so while it exists at higher energy like of electromagnetism held in quantum wells with energy neither created or destroyed, with the general expansion of thermodynamic entropy there would seem to be the necessity of gravity winding up the cosmos or it would wind down over infinite time and it hasn't. It seems all is connected up, and in subatomic physics it's well known that as you go from the lower energy force like the weak force to electromagnetism and then the strong force more and more conservation laws are in use. Electromagnetism has laws like electric charge and energy conservation well observed, and the strong force has all that's encompassed by electromagnetism plus more laws like conservation of isotopic spin and baryon number. This seems to fit the idea that all is made of lower energy fields energised up to higher energy. Each force has all the energy and features of its own energy level plus some more than the forces below it. On the other hand, the weak force seems to be the strongest force because it powers atomic reactions. The strong force is only attractive so it can only power the strong expansion of the atomic bombs or of atomic power by squeezing in the central weak force which powers radioactivity, the glorified name for expansion of the mass of the reaction. Like squeezing the juice from an orange, the strong force is attraction that can only implode to then heat up the short range more dense weak force to power it's radiant heating just as the lower energy only attractive force of gravity causes the heating of the solar power. Does gravity or fusion or the weak force power the solar heat? In truth it's all three, while to say the weak force is so weak it isn't the cause of the power seems improbable, because if we only allow that the weak force is weak and the strong force is actually implosive, there's no outward expansion to power the atomic reactions. For this reason I believe the weak force is weak in name only and in truth if it's the cause of atomic reactions it must be strong, even stronger than the strong force in order to overcome its implosion. The weak force is thought to be weak because it's a short range force. In truth it may be weak at long range because in order to explain it's weakness some have taken this strong force of short range (thus great strength) and subtracted a second strong component of the field to find the strength we see, the classic method used to find the electron's mass and charge so numerically well of "renormalization". If the weak force powers the atomic reactions and it must be strong, in truth it may be the strongest force there is. Going from electromagnetism to the strong force to the weak force the range decreases, and it seems that gravity would be longer range than electromagnetism so the cosmos won't leak out the thermodynamic heat and the cosmos would wind down over infinite time of energy being neither created or destroyed. Gravity fits in this pattern because being the weakest, gravity obeys the least conservation laws, e.g. it doesn't obey conservation of electric charge. The gravity may outdistance the light to hold it in just as the electric field out reaches the strong force, and the strong force is stronger than electromagnetism which is stronger than gravity, thus if the weak force is the shorter range force it seems in some sense it would be the most strong, even if only at close range or even perhaps in some higher dimension. Even so the conservation laws act like the weak force is weak with the fewest conservation laws for the weak force in subatomic physics.
..
Gravity is long range (to hold the cosmos together without leakage), electromagnetism is shorter range, the strong force is shorter and the weak force has the shortest range;
..
Yet gravity has the least conserved, then the weak force then electromagnetism, then the strong force. This is not the same general motif. Why? Perhaps it actually seems these are unrelated motifs but they actually may turn out to be the same with more indepth higher energy resolution like with the LHC.

By the first idea that the conservation laws are conserved from lower energy on up, with more intrinsic strength at close range it's possible if the weak force is actually strong, so the conservation laws, being a general increase of complexity with more energy like many things around us (e.g. the history of patents in invention, in evolution, or science) would perhaps have more of the conservation laws being obeyed in some form if at least at close range perhaps in another way to move even if they are more bottled up for some reason than the same consevation laws of the other forces. If it's true that conservation laws are important to physics, and that the weak force is actually strong this would seem to be so, or a possibility.



How to Save More Heat, To The Power Vendor, You!

There are now inventors who are using large acoustic lenses to bend sound waves around and away from rooms to hope to make a zone with no noise at all. Or perhaps even a hat you wear that's much cheaper than antinoise to always have quiet, a solid gold room you wear! And this is believed to be of use for submarines to make sonar not bounce off the sub but rather to bend around it and so the sub would be invisible to other sonar. Another possibility under consideration is to make large heat lenses around houses, perhaps an inflatable dome that would not only bend most of the summer heat away from the house from all directions, it would also capture the heat via collectors in the dome and put it back in the power grid. Thus there would be a reduced heating bill and more money from the electricity. The general shape of the heat shield would bend the heat rays away and focus them to either collectors or just into wires or optic fibers. At christmas and when the boss is mad, if the shield was reversed you may be fired with ambition!


Another idea under construction is an inflatable hurricane shield around houses that would connect to a permanent foundation flange around the base to stop flooding and that would also be like the hurricane window guards in use that are kevlar to save the windows from high speed projectiles just by hanging up this venetian blind. iboom.com says the kevlar is strong and not heavy so it would be held upward and filled with air to deploy and once it was over the house the roof would hold the shield up, protecting the building from both the flooding and most of the damage from the storm. For the best protection air pumps could continually inflate the shield while the storm was in progress though this would not be necessary. Another possibility might be a retractable shield of kevlar like the old convertible tops for automobiles. Materials are one key to making hurricane proof buildings. Buildings survive storm after storm (without hi tech science!) in some regions where hurricanes are common because they are of concrete, so billions in expensive research (some is!) building computer simulations to survive storms with all the expensive walls and roofs and other structures some have built may be unnecessary.

Even though a kevlar shield would itself cost a lot, some sites say the price of kevlar and other materials may improve as time goes on e.g with Fullerines, and it would be an insurance boost, especially for large buildings like mills because of economy of buying the kevlar in volume compared to the value of buildings saved. And unlike concrete this could be retrofitted or with the low weight of kevlar might be airlifted from one zone to another before the storm hits to save on the kevlar by reusing it where most of worth. All the foundations to secure the shields from floods might be permanent in each city but since hurricanes don't hit two cities at the same time they wouldn't have to be shielded at once so all the shields may be moved to just the one city about to be visited by the storm like by train, saving money. This may be the cheapest way to retrofit large buildings.

It's been the second beautiful summer in a row in 10 years where I live, not too hot. Even so if you go out in the heat you may see those bands you wear on your head that have fibers to absorb a lot of water when you soak it in the bowl of water, and this gradually trickles down your brow so the ad says, cooling your head. In actual use like the water cooled pillow filled with water you find it soon runs out of cooling power because the bandanna runs out of water or because of no evaporation like the pillow. If trickles of water were constant either the bandanna or the pillow would cool well, if you spray your face in the heat it cools well even without cooling the water which is only for the hottest days. Even so it would be easier if the bandanna continously cools your head because I sometimes forget to spray in the heat or have to do something else, OUCH! A solution that's been devised for the trickle of more than biz cash flow may be a hat with a water resevoir in the top sort of like the first air conditioner built in india in the 800's or so that used a rug hung on the side of the room where a wall would be, the rug had a trickle of water in the top from a small trough across the top side and the more constant monsoon winds blowing through the room cooled the water in the rug to cool the room by many degrees, like 30. I always wanted to be a water cooler and a tower for bottled water, The lake has no more than me! There are other cooling systems, but unlike other coolers this uses the trickle of gravity from the resevoir so it doesn't need a hand pump to compress the air to raise the water from a backpack.
