Graphene is a "sheet" of a single layer of carbon atoms - a material obtained by Andrey Geim and Konstantin Novoselov in 2004, which has got many unusual properties, thanks to which graphene is considered today as one of the most promising materials for creating new non-silicon elastic electronics. The main interest is the connection of the unique elastic properties of graphene with the electrical characteristics of the material. As scientists say, development and producing of it would become a revolution. Firstly, it is very durable - 300 times stronger than steel. He will be able to withstand the weight of an elephant, and this is far from the limit! Is it necessary to say where such a property can be applied? Bulletproof vests, super-strong houses and even spaceships! Secondly, it is very light - when you create it, you will literally see that it flies, because it is lighter than air! Super-strong and light aircraft are becoming real The most important property of graphene is electrical conductivity. It is 8 times higher than that of silicon, from which all transistors are currently made, that is, all electronic boards in general! And it turns out that a lightweight, durable and ultra-fast computer will replace it. It will not occupy even a tenth of the area of the current one. Also, graphene has excellent adsorbing properties, just like activated carbon. In my view, graphene is a really underrated breakthrough, which will lead us to new era of materials.

A Doctor's Dilemma That’s a dilemma close to Trolley problem. You have a choice to save 5 by killing one(and get +4) or do nothing and have 5 corpses instead of one. And also there is a variation, there you push a fat man on the rails. That’s changing opinion about the case, because it is a direct action. In our dilemma the action or inaction is not giving patient 6 medical care. You can consider it as an action, because you should do it since you are a doctor. Or you can consider it as inaction, because you’re doing nothing. Choice one (Doing nothing). Do as Kant said. You can’t do anything with life of a human being since it is invaluable. The patient 6 is living as it should be by nature and patients 1-5 die as it is their destiny. Choice two. Utilitarian. Saving 5 is more than saving 1, so you should act. Death of 5 people is worse than death of 1(Absolute countings). The drawback is that you’re becoming a murderer. Choose wise
