>The most widely discussed talk at the Indian Science Congress, a government-funded annual jamboree held in Jalandhar in January, wasn't about space exploration or information technology, areas in which India has made rapid progress. Instead, the talk celebrated a story in the Hindu epic Mahabharata about a woman who gave birth to 100 children, citing it as evidence that India's ancient Hindu civilization had developed advanced reproductive technologies. Just as surprising as the claim was the distinguished pedigree of the scientist who made it: chemist G. Nageshwar Rao, vice-chancellor of Andhra University in Visakhapatnam. "Stem cell research was done in this country thousands of years ago," Rao said.

Why do physicists have to pretend some things are more complicated and mysterious than they actually are?
What I am talking about specifically are 1: Black holes and 2: Stupid Schrodinger’s cat
1: Black holes are obviously just huge stars that are so massive that light doesn’t escape. No need to talk about event horizons, infinity, singularity and all that quackery.
2: Schrodinger’s cat is dead if the atom has decayed. Quantum physics says the atom is both decayed and not decayed until observed. Well the cat is dead in that case because it’s not like the atom not decaying undoes the part decaying.

When I perceive a slice of pizza I am struck only with ideas of a pizza-like fashion. For instance, the appearance of cheese, the smell of tomato sauce, and the feeling of hot grease. Nowhere in these ideas is to be found anything material. Of course if there are ideas, then there must be minds to perceive them, so we can see that, as empiricists, we really only need two ontological commitments: ideas exist and minds exist.
Great, so that's out of the way. Now we must ask wherein the source of these ideas lies? After all, given the consistency between my ideas of the world and the apparent consistency between my experiences and the experiences of other minds, it stands to reason that their must be some common source behind them.
Maintaining the ontological simplicity that we already have, there are three possibilities. First, the source of the ideas is my mind. Second, the source of these ideas is some other idea or ideas. Third, the source of these ideas is some other mind.
The first possibility is implausible, for I do not have the mental capacity to imagine the whole world, yet ideas of the world exist even when I'm not think of them. As well, I cannot help but notice that I have no power to change the ideas the strike me. I cannot force myself to perceive a pizza in the way that I perceive my keyboard in front of me. So I am not the source of the ideas.
The second idea is unhelpful since it opens us up to an infinite regress with no real explanation in sight.
That leaves us with only one possibility, that the source of these ideas is some other mind. A very great mind, in fact, that would be capable of imagining all of creation at once. But what could such a mind be besides God? There is nothing else it could be, therefore God exists.
so anons here are claiming that life was created just by pure luck and chance. so why wasnt air planes/ cars/ computers etc created just by luck. they are way simpler than life.

I'm a Semen Analysist and I'v been frequenting this sight and decided to make an exciting announcement you might not hear about for a year or two, here, as an exclusive gift to the community that has entertained and made my life better for the duration of most of my middle ages.
Race has been a very complicated subject which for a long time now, people aren't really willing to talk much about in the scientific community for obvious reasons. People have tried to link DNA directly to race for a long time now, but, apparently DNA isn't entirely the force which dictates race. In fact, most of the major physical features and behavioral features a person will have is based off which sperm cell will survive into the egg of the female. Individual sperm cells do behave somewhat differently, into bunches. These bunches, which a single male can end up producing dozens of in a single sample of sperm, will end up moving in groups and competing with other groups in such a way that this pattern decides what sperm cell gets to make it inside the egg.
This was already a theory on the table developed by previous analysis and shared in the community through publications of different science journals, but, now multiple female volunteers who came from different backgrounds and different races, have managed to, not through genetic manipulation, but, by manipulating which specific sperm groups can make it into the egg, have all had children that look vastly different than the parents. This means that by identifying different sperm groups by the behavior of the sperm groups, we were able to separate them while keeping them alive, incriminating a female, and making that female who's body naturally tries to resist those specific sperm groups by giving advantages to other groups, have children of races that aren't the race they are.
We can now control if we want, what race our children are, without ever having to change DNA. Enjoy.

I spent a good amount of time in an engineering school before realizing it was a scam. I went to engineering school thinking I was going to learn to build some cool shit out of wires and old engines and all I learned was purely theoretical knowledge useless in the real world. Engineering physics is just fucking useless, because it considers all situations as being ideal, but we will never work with ideal conditions in the real world. I spent 5 fucking years in engi school and I learned nothing practical, absolutely nothing. All engineers I have met said they never needed calculus in their work. A guy who spent one year working on civil construction is more capacitated than a guy who spent 5 years in engineering school.
