What is 1 YouTube video you think every person on Earth should watch?

Light travels at about 1 foot per nanosecond.

Hold your hand up 12 inches from your face: you’re seeing your hand as it was a nanosecond ago. Everything you look at is, to one degree or another, in the past. The farther away in space, the more ancient in time.

You can’t see the Sun as it is now, but you can see it as it was about 8 minutes ago. You can’t see Alpha Centauri now, but you can see it 4.4 years ago. You can see the Andromeda Galaxy as it was 2.5 million years in the past. And so on.

With powerful telescopes, we can see galaxies whose light has been traveling to us for more than 13 billion years. We see them shining in a universe that’s still young, where gravity has just begun to pull matter together into stars and galaxies.

We can see something even more distant, and more ancient, than the first galaxies. If we peer out far enough, in between the galaxies, we can see parts of the Universe that are so far away, it has taken the light from that distance almost the entire age of the cosmos to reach us.

1/ Recently, I learned about the concept of ‘struggle porn’. This refers to the fetish of sacrificing nearly everything (health, relationships, time) for your startup. I fear that this label is creating more harm than good.

2/ @nateliason wrote a fabulous article about this topic, which first introduced me to this concept. Everyone should read it:

3/ @alexisohanian also recently spoke about struggle porn, though referring to it as ‘hustle porn.’ (as the co-founder of @hustlefundvc, obviously I take issue with this pejorative definition of ‘hustle’, but that’s another topic)

4/ Struggling in itself isn’t necessarily bad. Let’s be real here--if you’re going to start a startup, you will struggle. Founders should expect to work harder generally than employees. You will be challenged in many ways and also be super rewarded in others. This is normal.

5/ However, if you are over-indexing on hard work without clear purpose and degrading your mental health/relationships in the process--then this is very bad and we obviously should not celebrate this behavior.

RANI NAIKI DEVI AND THE BATTLE OF KASAHRADA

Mohammad Ghori, the young Ghurid Prince conquered Ghaznavids in Afghanistan in the year 1173 CE. He conducted some successful raids into the Indian territory, which even Mahmud Ghazni & the Persians couldn't do.

First&foremost,Ghori invaded states of Multan &Uch in India.After this he turned to southern states of Gujarat &Rajputana.Everybody knows this about Ghori,but what most pple r unaware of is the defeat he suffered at hands of Chalukyan Queen Naiki Devi in 1178 Battle of Kasahrada.

When he marched southwards, his first target was the prosperous fortified town of Anhilwara Patan.
It was the capital of Chalukyas(also known as Solankis of Gujarat) which was established by Vanraj of Chapotkata Dynasty in 8th century.

American historian Tertius Chandler states that it was the 10th largest city in the world at that time. The history of Chalukyas has been written by many historians, but the valour of the Great Queen Naiki Devi remains unsung.

Born to the Kadamba King Paramardin of Goa,Naiki Devi was well trained in sword fighting, horse riding, strategy & every other subject of Statesmanship. She was married to King Ajaypala of Gujarat who sat on throne in 1171CE. Unfortunately,the King died within 4 yrs of his rule.

Rani Chennamma of Kittur was one of the first women rulers of India who fought against the might of the British Empire in 1824. Rani Chennamma was born in 1778 in a small village of Kakati in Belgaon distt of the State of Karnataka.

She was born into the Lingayat Community to a man named Dhulappa Desai. From a very young age she was trained in horse riding,sword fighting, archery and diplomacy. At a very young age of 15 yrs, she was married to the King of Kittur and became the Queen of Kittur.

It is said that King of Kittur Mallasarja was once moving around in the neighbouring kingdoms to find support to fight Tipu Sultan. It is then, when he came across Chennamma and he immediately got attracted to her sheer confidence and bravery.

Rani Chennamma and King Mallasarja had a son together who died very soon after the death of King Mallasarja in 1816. As the Queen of Kittur, Rani Chennamma immediately adopted Shivalingappa as her son and declared him the heir to the throne of Kittur.

This did not go well with the British East India Company who was enforcing the Doctrine of Lapse those days, according to which the adopted children of the Indian rulers were not allowed to become their heirs and if the native rulers did not have children of their own, their...
