How did the term rednecks originate?

August 25, 2016 by manshu Leave a Comment

I’m currently Rewiring Your Brain, which is a fascinating book on how can you go about change how you feel about certain things, and remain optimistic throughout difficult times.

The book touches upon good dietary habits in quite a lot of detail and I was quite amused to come across how the term redneck came to be.

Relevant excerpt:

Vitamin B3 (niacin) is involved in as many as forty different biochemical reactions in the body and the brain. One of its principal effects is to participate in the process of increasing red blood cells, which carry oxygen to the brain.

It also is involved in the pathways for ATP, which, as I mentioned earlier, is the cells’energy substance. In moderate doses B3 lowers blood cholesterol, and in high doses it causes dilation of the blood vessels, increased blood flow to the brain, and decreased blood pressure.

Niacin can be manufactured from L-tryptophan, which, as I have noted, is a precursor to serotonin. The amount of L-tryptophan that is converted to niacin depends on your diet. Niacin and L-tryptophan should be balanced in your diet. A severe deficiency of niacin causes a condition called pellagra, which leads to dementia, diarrhea, and dermatitis. The dermatitis symptoms include a condition of extremely red skin.

Here’s a little factoid with which you can entertain people at a party: the term redneck has its origin in niacin-deficient white field-workers. Due to the deficiency, they developed a red “necklace”on the skin of their necks.

How do centipedes reproduce?

July 26, 2016 by manshu Leave a Comment

I came across an interesting thread on Reddit which asked how centipedes control their legs, and it is quite amazing because their brain sends a signal to walk, and then each segment has a small brain which controls its own legs, and acts as a brain to it.

A little curious; I searched for more information about them and apparently they can never step on their own toes, but then how centipedes reproduce is far more curious.

An excerpt:

Male specimens initiate reproduction by churning out tiny webs. They use these webs as vessels for packages of sperm, which they leave for female centipedes to retrieve. The females then insert these packages into their genitals. They set their eggs down below logs, stones or tree bark, and sometimes even in the dirt. Many female centipedes do carefully watch over their eggs, but this behavior depends on the exact species. Egg-laying occurs in warm times of the year.

Will the king catch your pawn?

July 24, 2016 by manshu Leave a Comment

I did an interesting exercise from learning about endgames in Silman’s book, and it talks about how to shortcut your way to calculate whether the enemy king can stop your pawn from queening.
It is an amazing technique and is somewhat indicative of the mathematical beauty of chess as well.

If you see the position below, the way to calculate this is to create a 90 degree triangle from your pawn to the diagonal edge of the board, so here one that goes from a4 to e8 and e4.
If the king is within the triangle then you won’t be able to queen, and if the king is outside the triangle then you will be able to queen.
What’s amazing here is that in the setup I show here, the king closest to the pawn at b3 won’t be able to catch it because it is outside the triangle but the other two will be able to catch the pawn because they are right on the edge of the triangle.

Hodor and the impossibility of backwards time travel

May 24, 2016 by manshu Leave a Comment

Unlike most people who watch Game of Thrones, I wasn’t heart-broken by Hodor’s gut wrenching death, but instead it left me puzzled, and I was initially unable to put a finger on my source of confusion.

For the two of you who don’t watch Game of Thrones but are reading this post, a little background on Hodor.
Hodor is a mentally disabled character in the show who is only capable of saying “Hodor”, though he understands what other people say. He is the stable boy of one of the royal families called the Starks, and is like a valet to one of the Stark boys called Bran Stark.

The mystery of why Hodor can only say Hodor was explained in the last episode. Bran Stark who is physically disabled and can’t walk is trapped in a cave with a bunch of white walkers trying to get there and kill him.

Bran has the capacity to travel back in time, and watch events although the people there can’t see him, nor can he interact with them. Additionally, he has the ability to get into the minds of other people and animals and take control of what they do. This ability is called warging.

Towards the end of this episode, Bran wargs into the mind of Hodor to make Hodor pull Bran out of this white walker infested cave, while simultaneously going back in time, and witnessing a scene from the past where Hodor can still speak and act like a normal kid.

The present Hodor pulls Bran out of the cave, and blocks the door to stop the white walkers from coming out. Bran’s friend yells repeatedly at Hodor to ‘hold the door’, and at the same time the young Hodor starts to get a fit while he yells ‘hold the door’.

The white walkers are able to punch holes in the door, strangle Hodor, and kill him, while the young Hodor is having a fit, and screaming ‘hold the door’ repeatedly, which gradually morphs into ‘Hodor’ until he stops screaming upon the death of the current Hodor.

This is a very well done scene, and can be quite saddening specially from Bran’s perspective because not only does Hodor eventually die saving Bran; he lives most of his life mentally disabled because of Bran.

However, Hodor got mentally disabled because he witnessed his own death while rescuing Bran, but he would not have been rescuing Bran had he not been mentally disabled in the first place.

So, it’s necessary for Hodor to die and witness his death to be disabled, but it is also necessary for him to be disabled to die and witness his own death.
I believe Bran shouldn’t feel bad after all, and this is also the reason scientists say backwards time travel is not possible.

Why do Greek statues have such small penises?

May 22, 2016 by manshu Leave a Comment

I’m sure you have noticed it, and perhaps you’ve even wondered why; I didn’t think I would ever find a reason for it until I stumbled upon this article explaining why Greek statues have small penises. 

“Greeks associated small and non-erect penises with moderation, which was one of the key virtues that formed their view of ideal masculinity,” explains classics professor Andrew Lear, who has taught at Harvard, Columbia and NYU and runs tours focused on gay history. “There is the contrast between the small, non-erect penises of ideal men (heroes, gods, nude athletes etc) and the over-size, erect penises of Satyrs (mythic half-goat-men, who are drunkards and wildly lustful) and various non-ideal men. Decrepit, elderly men, for instance, often have large penises.”

Only grotesque, foolish men who were ruled by lust and sexual urges had large penises in ancient Greece. Art history blogger Ellen Oredsson notes on her site that statues of the era emphasized balance and idealism.

 “The ideal Greek man was rational, intellectual and authoritative,” she wrote. “He may still have had a lot of sex, but this was unrelated to his penis size, and his small penis allowed him to remain coolly logical.”

 

Makes sense.
