As Isaac Asimov once said, “The saddest aspect of society right now is that science gathers knowledge faster than society gathers wisdom."

No one fits the saying, "you either die the hero or live long enough to see yourself become the villain.", better than this man, Fritz Haber.

I learned about this guy during an ethics in science class I had to take in college. One man encapsulating our highest highs and lowest lows as a species.
Humble Narrator
This is a perfect illustration from human history showing how "gray", or nuanced, the world really is. Great video and message, thank you.

Brilliant video. Very insightful conclusion at the end.

Who knew a paragraph in our chemistry textbooks mentioning Haber’s process had left out so much rich history, euphoria and sadness. Thank you veritasium for telling us such amazing stories.

It's incredible the impact this one man had..

I think his story is the perfect example of how being short sighted is one of the most dangerous things you can be. Man never really thought at depth at what he was doing until it was too late.

"He who increases knowledge, also increases sorrow" or - " we were so busy wondering if we could, we never asked if we should!" He simultaneously solved the human problem at either end. We live like a firework burning brightly, but only for a brief moment in time. Then darkness.

I'm glad you guys covered his story. I live in Ludwigshafen, the birth city of the BASF, and for most of us, it's a known fact that the BASF made one of its biggest breaks by producing Ammonia. It would later on lead to the BASF becoming one of the biggest global players when it comes to chemical companies worldwide.

It's crazy how desperately we want to categorize people as either heroes or villains.

"He is probably one of the most impactful and tragic scientists of all time."

I live in Syria, when the war started , fertilisers started to dissappear and farmers had a hard time with their work , corrupted people who had access to fertilisers sold it to terrorist groups.. the government then was trying to give it to only farmers, but the prices also went hight cause of what happened. I used to get scared when I saw a truck full of fertiliser bags that's how many attacks happened back then , but my dad is also a farmer so I have mixed feelings towards this whole thing .

there's a way how Derek tells us stories whilst giving us knowledge. it's just amazing how he spends so much time on research and getting these videos right. This is one of the best videos from this channel. Definitely in top 10.

He is the example of a person who wants to help everyone the best it can, without much control of the rest

This could be your best video ever because of its immaculate writing, excellent narration, and that touch of humanity at the end.

It always amazes me how Veritasium can tell you about fascinating topics that you didn't even know existed. After every video I feel like I can understand the world at least a tiny bit more.
The Rest Of Us
Awesome video, thanks so much! In Germany most high school kids know Haber’s story as a cautionary tale.
