A Few Answers To Questions You Always Wondered About

How do mathematicians know that they’ve correctly solved a complex math equation when other equally skilled mathematicians cannot?

Here’s an analogy. Let’s say you’re trying to find the solution to a very difficult maze. Everyone might be stuck trying to find their way out, but you’re the first to find the solution. How do we know your solution is correct? You showed us the path – it’s easy to verify that the path is correct, even though finding it is hard.

It’s the same in math – finding a solution is hard, verifying it’s correct is easy.

Another example is Sudoku – it’s hard to solve, but checking whether a solution is correct is easy.

It’s true that more difficult math problems might be more difficult to validate, but it’s still easier to validate the correctness of a solution (typically a proof) than to find it in the first place.




How does sodium pentothal a.k.a truth serum make people tell the truth? 

It reduces brain functions and makes people more susceptible to pressure to tell the truth. It doesn’t force people to tell the truth so much as it makes them have less control over what they say & think. Similar to how you may be more talkative or honest when you’re drunk, since you have fewer inhibitions.

Remember the saying “the easiest version is the truth”? This is true in our brains as well. It’s harder for the brain to think of a lie than to tell the truth and it requires a higher level of function. It makes sense when you think about it: to tell the truth you have to remember something, to lie you have to remember that and think of something else.

Drugs like sodium thiopental lower higher cognitive function. This makes it harder to lie. An experienced interviewer can then more easily spot that you’re lying as it will become more obvious. Your lies won’t be as good and won’t be as easy to think of them. They can use that to figure out what you’ve said is true and what isn’t.

However if you never say anything, they can’t learn anything. Though if someone is breaking out the sodium thiopental, they’ve probably been using sleep deprivation and other fatigue techniques as well. Once you start talking, it becomes very hard to lie accurately while under the influence.

During a police interrogation, can you actually get away with not saying anything until you’re provided with a lawyer?

In the US, the sixth amendment to the constitution says the following:

In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the Assistance of Counsel for his defence.

Brewer v. Williams (1979) held that once adversarial proceedings have begun against a defendant, he has a right to legal representation when the government interrogates him.

So basically, yes, it works like it does on TV. At least, it does in the States.

Now, in practical matters, the police are allowed to lie to you. There’s nothing stopping them from trying to convince you that you don’t need a lawyer. You could say to them something like “I think I need a lawyer,” and they could say something like “Why do you need a lawyer? Lawyers are for bad guys. You aren’t a bad guy, are you? We just want to get a bit of information”



What are the inner thoughts of a person suffering from Anoerxia?

I lost around 50 pounds in a bit less than 3 months at my worst, must have lost 60 pounds in total. It started very slowly, as I got used to everything, as I eliminates food. But once I got the hang of it, it got fast terrifyingly quick. I guess I had the predisposition, I can get sickeningly single minded with my purpose.

I have, however, wonderful parents who acted in time and while I was diagnosed with atypical anorexia, although my lowest Bmi was 17, I still had my period so never got diagnosed with anorexia nervosa in itself.

I don’t know how to qualify the way I viewed myself. Days I knew I was too thin and others where I viewed myself as in need of losing weight. Small things, skin roll when sitting, bloating, skin pinching, that made me obsessed over every ounce of fat.

I don’t think I viewed myself as fat or obese, necessarily. I was aware and unaware of being thin. I knew my ribs sticked, I knew I looked I’ll. But the need, the will, the absolute triumph I felt when my weight dropped trumped everything else. This feeling mattered more to me than the consequences, I felt important, I felt good and in control.

And seeing and feeling my ribs, my hip bone, having a thin waist line. It was both soothing and comforting. I craved the touch of my fingers over the bones. Seeing my weight go up even by a pound, was an experience so… Traumatic, each time. I felt like a failure, like a worthless pig who had no control over herself. Not eating, enduring the hunger was my quest for control back in a period where I felt I had very little of it. It felt empowering that I could control the most basic of instincts. I thought I was strong each time I ignored it. I genuinely thought myself better than other people, while being so so jealous. I was miserable, in a twisted form of happiness that just shattered over time.

And then, even when you realize you’re too thin, you can’t stop. The vanity of being thin is such a small part of the whole thing… It’s not about your appearance anymore. I did not care about what I looked like, what I felt like. I cared about what other saw in me and to the me of that time it was fat. It was ugly. It was bad, and awful, and I just projected myself. Every thought I had about myself I threw it on others and then comforted myself in believing I was a superior being who could ignore instincts. Oh how I envied them and hated them.

There’s nothing logical in this thinking process. It’s just the visceral desire of introducing control in your life. It’s like believing you can extinguish fire with oil and you keep repeating the process, completely unable to see how violent the inferno became. And you can only realize much too late that the fire you were confronting in front of you made a full circle, and you’re trapped. You want out, but you just have the oil in your hands to put it out, so you just make it brighter and stronger.

Could someone who has steadily and determinedly studied MMA for two years survive in prison?

Do you mean survive based solely on their MMA prowess? Nope.

Daryell Dickson Meneses Xavier was a Brazilian Jiu-Jitsu instructor who was accused of sexually abusing his 1 year old stepson, leading to a seizure and eventually the child’s death.

Brazilian Jiu-Jitsu is the the martial art that the winner of most of the early UFCs used. And is now an integral part of almost every MMA fighter’s training.

Despite almost certainly being the best fighter in the jail, once the other inmates discovered what he was accused of, he didn’t stand a chance.

According to reports, at his initial 30-day incarceration, the perpetrator is said to be brutally raped by his 20- fellow inmates as he awaited for a hearing of his case before a presiding judge – receiving vigilante justice. After the initial assault, Xavier was then tended to by the jail’s medical staff with numerous sutures across his back and noticeably on his anal area.

However, he was then instituted back to the prison where he received another round of prison justice, raped and otherwise abused for the second time tearing out the fresh stitches from the wounds, brutalizing him more. Injuries became more prominent over his entire body especially on the region of his back side.

An image of Xavier following the savage attacks was posted on the internet – attesting the form of justice he has undergone from the bloody stains on his back.

No matter how good a fighter you are, numbers will always win. An amazing fighter might be able to take on a higher number, but if you have a whole cell block against you then you’re out of luck. I imagine that BJJ, which relies heavily on grappling and submission, is especially ill suited for multiple opponents.
