Self Driving Cars

“Are our social and legal structures ready to deal with self-driving cars? Or to put it another way — are we ready?” – asks the Los Angeles Times.

Here’s the rational way to think about this. Self-driving cars are the safest way to go on the road, just as flying is the safest way to travel period. There have been crashes and deaths with airplanes but we don’t ban the planes. Statistically, self-driving cars are the safest vehicles on the road by far. So why ban them?

But who do you blame if someone is killed?

That’s the problem.

In aerospace, the blame is studied. Was it pilot error, mechanical error, air traffic controller error, birds or what? Then suggestions, findings and corrections are made to make it better.

Self-driving cars should have the same rules, except here there’s no “driver” error. You must consider “software error,” other person error, other driver error, other circumstances, and so on. Then suggest findings and corrections can be made to make it better.

Should we really scrap the safest travel on the road because of a fatality?

Monkeys are not friends

Here is a story posted today on the UK’s Daily. The story is also carried in multiple news outlets. I’ll have a commentary below.

A newborn baby has been found drowned in a well after allegedly being snatched away by a monkey in eastern India.

The infant was sleeping under a mosquito net at his home in the eastern state of Odisha on Friday when he was taken by a rhesus macaque monkey.

His mother claimed to have witnessed the monkey take the child away, but was not quick enough to get her baby back, local police said.

On Sunday, the 16-day-old baby was found dead in a neighbour’s well in Talabasta village, near Cuttack, Odisha, and authorities believed the monkey may have dropped the boy in the water.

I lived in India several times in my life and I had one of these macaque monkeys take my eyeglasses right off my head. He and other of his “cronies” ran off with them. All we ever found was one lens – a huge scratch on it. Until I had them replaced, I was without clear vision!

These Macaque Monkeys are a serious problem.

These monkeys are NOT cute. They are a menace!

If you dug a deep tunnel or were somehow stuck in an impervious container in the exact center of the Earth would gravity pull you one way, but then pull you back the other way?

Well, you already know it’s pretty hot down there so you couldn’t do it, but if you could because your container was impervious, and you were suspended right in the middle, you’d be weightless.

Now a lot of Quora people are going to tell you all kinds of interesting things like how hot it is, or how if you jumped in the hole you’d slam into the sides because of Earth’s rotation and die. I’m just dealing with the hypotheticals.

By the way, here is the top of the deepest hole ever dug. The building that used to surround it has been abandoned and the digging process stopped. It’s called the Kola Superdeep Borehole.

The Hindu Caste System

In the dictionary used by Google Assistant, caste (pronouced kast), is a system “distinguished by relative degrees of ritual purity or pollution and of social status.” During British reign over the Indian subcontinent from 1876 to 1947, the practice was outlawed.

The caste system, though against the law, still holds many people down in poorer parts or religious strongholds of Hindu Society.

This wasn’t always the case. Hindu religious scriptures, a group of writings collectively called the Vedas, broadly and variously define caste not by social status but by natural proclivity. Religious scholars in the field say we’re all divided into four categories. Not just Hindus, but all of humanity.

The four castes are:

  1. The laborer.
  2. The businessman
  3. The politician and organizer
  4. The thoughtful person.

The Indian subcontinent, is a large peninsula that protrudes from southern Asia. It comprises of several countries, India being the most prominent.

These divisions are called: Shudra, Vaishya, Kshatriya and Brahmin and you’ve just had your first lesson in Sanskrit for the day. Sanskrit is similar to Latin in that the language exists and scriptures are written in the language, but it’s not a spoken language anymore.

Originally, culturally and historically, caste was not determined by birth or social status but by natural propensity. Thus if someone born in a laborer family had a proclivity to be a politician, or businessman, or priest, and earned the qualifications through apprenticeship, then so be it.

In fact, one Indian guru, A.C. Bhaktivedanta Swami Prabhupada, traveled to the United States in the early nineteen sixties. By teaching and initiating disciples among young Americans, he created a class of Brahmins from ordinary people that gravitated to his religion called Krishna Consciousness. This relatively small religion migrated around the world and still has followers to this day.


Swami Prabhupada founded the Hare Krishna religion in the West

That Prabhupada would introduce ancient Indian teachings in the United States clearly suggests that in the mind of some Hindus caste is not by birth, but by born proclivity. Anyone, Prabhupada believed, could become any member of a cast simply by exhibiting a tendency and learning about the religious beliefs behind it all.

Though compared to most religions the Hare Krishnas remain small in number, they are respected in various communities in India, but not by all. An example of a community that does not accept non-Hindu born people as Hindu-converts is the city of Jagannath Puri on the East coast of the Indian sub-continent. There is a big temple, much like the central church of a religion in the West. This is the Temple of Jagannath and is visited by Hindus who make the pilgrimage from all over the world to see it. The temple authorities, however, don’t allow anyone who was not born a Hindu to set foot in the temple. It is strictly enforced by multiple levels of security. “White Hindus” (or any other color of non-born Hindus) are not allowed to defile the temple. Even an Indian born Muslim is not allowed in the temple. You must be born in a Hindu family to be allowed inside.


The popular temple of Jagannath in Puri, India. Non-Hindus are not allowed inside.

It is tantamount to someone born in an Islamic family who converts to Christianity, and not allowed in the church because of his or her birth. Even though most Christian communities would accept an Islamic-convert, there are people and groups who are racially tainted toward anyone who has non-white skin. According to people of this mindset, everyone from Europe or the middle-east, with non-white skin must be a terrorist. Often Hindus and Sikhs are mistaken as Muslims and experience discrimination based on perception.

Never mind that in India and most other Asian countires there are Chrisitians, Jews, Hindus, Muslims, Sikhs, Buddhists and just about every other religion you can think of. The ignorance has become so deep, even in the wake of the age of the Internet, that many people don’t even know there are other religions like Sikhs and Buddhists and Hindus. You’ve even got a United States President who vehemently and relentlessly tries to stop people from entering the United States from countries that are predominately Muslim.

Therefore, we can see that racism and prejudice exist among different cultures around the world. For example, I once visited Fiji, an island nation in the South Pacific. The indigenous population are predominately dark skinned. However, the British had a tendency to muck things up and so brought indentured laborers from India to help with the production of sugarcane, which grows like weeds over there.

As a result, fast forward a couple hundred years, the population of Fiji is split down the middle. You’ve got half the country native Fijians, and then you’ve got the Hindus, descendants of the Indians who were brought there by the British. They comprise the other half. They don’t like each other. There’s a lot of tension and mistrust on both sides. Sometimes they have coops if the wrong side gets elected to lead the country. Sometimes there’s murder.

Getting back to the original assertion of this article, regardless of prejudices of people of the world, every culture has something to offer. There is nothing wrong with unity and diversity.

One of things I’ve taken away from the Indian culture, besides their wonderful knowledge of spices in cooking, is that the caste system was an unfair division of society if taken because of birth or placement of one’s family, but that also there is a recognition that everyone is different, not equal. Someone wants to be a priest. Someone wants to be a businessman. Someone wants to be a politician, or a policeman, or a military person. Someone likes to dig in the ground, build houses, build skyscrapers.

These are the four castes. It’s going on all over the world anyway, whether we call it that or not.

Why not recognize this in children as they grow up? Why don’t we start helping, directing, encourage kids if we see, “Oh, he/she likes woodworking. Oh, he/she likes working on cars. Oh, he/she likes physics! He/she likes bodybuilding and sports!”Image result for making a table

Obviously, the American system of education is not doing nearly as well as some other countries, despite propaganda from politicians.

Perhaps, long before they reach college age, young men and women should have the training they need to step out into life and become a productive member of society that has a job doing stuff they like!

Below is a chart originally published in the British newspaper The Guardian. According to the data, and contrary to what American politicians might have you believe, the United States is not a leader in education by any means whatsoever. Is it time to try something else? If not the caste system, then at least something different!

Lose weight with less gravity!

You weigh less on the Equator than at the South Pole.

I saw a show once about a science researcher that traveled the globe with a small scale and an ordinary garden gnome, you know, like the one on Travelocity TV commercials.

At one point he weighed the gnome at the south pole and it weighed 309.82 grams. At the equator the gnome weighed 307.86 grams. The gnome was 0.6% lighter at the equator, which is further from the center of the earth’s core than the south pole.

The further you go from the core of the earth, the less gravity you experience. So if you want to lose weight without dieting or exercise, go to the equator!

Here’s the scientist himself weighing the gnome.

How did such an immense amount of water actually came to the Earth during its formation period?

There is not an “immense amount of water” on Earth. To we specks walking like ants on the surface of the planet it looks to be a lot of water, but it really isn’t.

To illustrate this I like to show the image below which shows the total water of all the oceans, lakes and rivers on the planet compared to the planet itself.

You can see from the above image, the amount of water relative to the size of the planet is indeed very little, almost insignificant. In fact, relative to the size of the earth, the ocean is very shallow.

This means that only a very small percentage of the collisions early Earth experienced needed to bring water to the planet. The vast majority of these early collisions did not result in the presence of water.

Why did people believe that water was an element?

Why did people believe that water was an element? Some cultures, like in Hinduism, still believe there are five elements: Earth, Water, Fire, Air and Ether.

It really depends on definition. We assume the word “element” has a specific definition that is universal in the English language, when that is not the nature of English. English evolves differently in the different areas of the world where it is spoken. Thus the letter we pronounce “zee” (Z) in America is pronounced “zed” everywhere else in the world that they speak English. Aluminum in the States is Aluminium in England. A gallon of milk in America is not the same size as an Imperial Gallon of milk in the U.K. In India if you say, “I am liking you too much,” it is a compliment. In the United States it would seem like an insult.

In the Hindustani version of English, an element is a state of matter. Thus you have solid, liquid, fire, gas and the mythical ether they say space is made of.

So I believe the answer to your question is it’s a question of regional definitions of the word.
