Submarines: From Raider to Wolfpack | Documentary | Ep. 01

Submarines had a great influence in military history and are technical masterpieces.

When submarines were first used more than 100 years ago, hardly anyone believed in their usefulness. Many admirals were convinced that the simple "submersibles" could not stand up to the powerful battleships. This changed in the First World War. For the first time, submarines operated militarily in larger numbers. The reconnaissance boats quickly become hunters that sink enemy ships. In British and Allied propaganda, the German submarine became synonymous with treachery, cruelty and inhumanity in naval warfare.

The German submariners were hailed as heroes at home. The image of the U-boat commander as a silent hunter did the rounds. This heroic glorification has little to do with the reality and the danger the crews find themselves in on every mission.

Submarines originated from a completely non-military idea, namely to be able to look at the world under water. In its history, the submarine was and is both a deadly steel monster and a vital shelter.
As impressive as its construction is, as terrifying is its destructive power. Hardly any other weapon triggers as many emotions as the submarine. It strikes from ambush and can tear the whole world into the abyss with nuclear missiles.

Episode 1 documents the beginnings of submarine development at the end of the 19th century up to the outbreak of the Second World War. Submariners, historians and military experts put the events into context.

Frequently Asked Questions

Is it possible to learn from the past and not repeat past mistakes?

Because we keep repeating the same mistakes, history repeats itself. We do not learn from our failures. We don't change. We become complacent. We settle to mediocrity.

History also repeats itself because we keep believing the same old stories. We are conditioned to believe in immutable truths and immutable rules. We cannot change them.

This keeps us from being able to think critically. To question authority. Questioning authority. If we don’t ask questions, we don’t grow. If we don't grow we stagnate. When we stagnate we make the same mistakes again and again.

History doesn't repeat itself, because we continue to make the same mistakes. History repeats itself because we refuse to learn from our mistakes and instead continue to make the same ones over and over.

You can end the cycle of history repetition by changing the way that you view the world. By understanding that nothing is permanent, you can see the possibilities. Everything is subject to constant flux. Everything is constantly changing.

To break the cycle, embrace uncertainty. To accept that things could go wrong. Accepting the possibility that we might not succeed. To accept that failure is a possibility.

Accept that you may never achieve your goals. Acceptance of this fact is okay. But, don't let it stop you from striving to improve.

You will always remain stuck in the past if you hold on to certainty. If you believe there are only certain truths, it will be impossible to move forward.

If you want freedom, you have to let go. If you want progress, you need to let go of control.

Who first said that people who don't learn history from the past are stupid?

We all wish to live in a world where everyone learns from the past, but there are more valuable things than learning from our mistakes.

You can't learn anything better than trying it wrong.

The real error is not making sure you do it correctly the first attempt.

As long as you keep making improvements, you'll eventually understand why you made those changes.

You might find out that it was easier than you thought.

If you're honest with yourself, you'll realize that your mistakes are just lessons. They are learning opportunities.

Thomas Edison experienced exactly that. He failed many more times before he invented the lightbulb.

He didn't let his failures discourage him. He used every failure as an opportunity to improve the design.

He developed the most well-known form of lighting we have today.

So, if you fail, don't get discouraged. Learn from your errors. Take advantage of them.

You can then try again.


What are three things that you can learn from the past?

History is full of examples of how we can learn from our mistakes. These lessons can be applied today to business problems and used as opportunities for growth.

The past teaches us that there is always another way to do things. There is always someone out there who thinks outside the box and takes risks that make them stand apart.

History also shows us that it's often the underdogs who succeed. When you feel overwhelmed, stuck or lost, think back to the times when they won.

Take a look back at the past to learn from it and make improvements for the future. Learn from others' successes and failures.

Use these lessons to help you improve your success rate.

How To

Accidental Inventions Lead to Penicillin Discovery

How did penicillin become a reality?

Penicillin was discovered accidentally when Alexander Fleming noticed mold growing on some bacteria cultures he had left out. He thought the mold might kill the bacteria, so he tried to find something that would destroy the mold.

He discovered penicillin could kill mold. Later, he realized that this new compound could also fight bacteria-related infection. Penicillin was one the greatest medical breakthroughs. It saved millions and changed medicine forever.

Alexander Fleming was unaware at first of the importance of his finding. No one else knew the same. Penicillin would soon be a powerful antibiotic.

Penicillin was discovered to be effective in fighting bacterial infections by scientists only after World War II. In 1945, the U.S. Army asked Dr. Fleming if he could use penicillin to treat soldiers suffering from wounds infected with deadly germs. Dr. Fleming consented to try.

Penicillin was effective against many types infections. It saved the lives of wounded soldiers in World War II. It saved many lives and helped doctors continue their work after the war.

Dr. Fleming had no idea that his discovery would have such an impact. He was just trying to prevent mold growth on the bacteria cultures that his research had taught him. He could not imagine that this simple experiment would lead him to such a miraculous medical breakthrough.

Many of the discoveries that are made each day don't seem like they add up to anything remarkable. They're just experiments done for no particular reason.

Look back on history and you'll see that even seemingly minor experiments can make all the difference.

It is often the most important discovery that seems to have no commonality. The discovery of penicillin is an example. Or photography. Or electricity. Or even computers.

It is not because someone has a brilliant idea. It happens because someone has a problem. They then solve the problem by experimentation.
