“How can we use an exothermic reaction to fasten two pieces of metal?”

If you have thought about this problem, then not only do you have the mind of an engineer, but I think that you should learn about an interesting process known as Exothermic welding! Exothermic welding is a type of welding that employs an exothermic reaction between aluminum dust and another metal to create a combustion to create a fusion. The advantages of this process include : Higher mechanical strength, no increased electrical resistance over time, and has extra corrosion resistance

Einstein’s general theory of relativity is one of the most astounding accomplishments in the entire history of human thought. When Einstein originally published his theory of special relativity in 1905, it only worked for a constant velocity. But what if we take into account acceleration? Einstein pondered that, and spent the next 10 years working on such a ominous issue. After he was finished, he published his General theory of relativity. In General relativity, All of space is like a bedsheet, and objects like planets are like marbles. By putting one on the bedsheet, we cause a disturbance, which affects other planets. Also, space and time are not separate but one in the same! This is how higher masses cause disturbances in time as well as in gravitation. In this end, gravity is not a force but a geometric disturbance. This effect accounts for gravitational lensing
