So we ended last episode at the start of the 20th century with special purpose computing devices such as Herman Hollerith’s tabulating machines. But as the scale of human civilization continued to grow as did the demand for more sophisticated and powerful devices. Soon these cabinet-sized electro-mechanical computers would grow into room-sized behemoths that were prone to errors. But is was these computers that would help usher in a new era of computation – electronic computing.

Actually, instead of the stated ~50nm, modern chips are down to 14nm feature size 🙂

Particle Config. says:

Hah!, I'm listening this course though a Tube Valve Amplifier, this episode sure adds some knowledge to my understanding of it!

Laggie says:

And our dumbest President in history, Donald Dump, wants to cut research funding and kill PBS.

A.O. Z says:

no mention of ABC?

Tomatnaufmaugn says:

so you are talking about the beginnings of electronic computing and you dont even mention Konrad Zuse?
also Transistors dont rely on quantum mechanics

Dick Steele says:

What about German computers? Soviet computers? And didn't the Brits contribute some great machines as well?

This series has bugs in it.

Dick Steele says:

What a great presenter, I really like her tempo and pronunciation.

Tathagata Mondal says:

Crash Course has become a high quality online university.

Quintus Dirks says:

while i find your videos very insightful, i do find it a bit problematic that all your illustrations are white, its as if black people played no part in history. feels very colonial

Jayashri Venketasubramanian says:

Could someone please explain- how can a component be made to switch state so many times in a second? What sort of input changes that fast, and how do those parts move? (sorry for dumb question)
Really love this host btw! 🙂

Conner Fields says:

It seems like covering systems theory and cybernetics relationship to computing would be a useful episode, or series of episodes.

Simon Krämer says:

Where is Zuse???

AgentMull says:

It bugs me that all the drawers behind you are empty.

Derek Tran says:

The lack of mention of the Atanasoff-Berry computer is distressing.

Jon Campbell says:

this is a great course

Jubraan Alkhalaf says:

What's really weird is that I had an ad about crash course before this episode 😝😀😄😆

Arsenticx21 says:

This makes me feel so stupid

Michael Roberts says:

I love this series so much, but it is probably because I majored in Electrical and Computer Engineering, so this is like my home.

Dacosss91 says:

I would like to point out an animation oversight at 2:01.
After the valve is closed, water would leak out in the other direction 🙂

Connor Macfarlane says:

I saw the butterfly effect on the desktop and instantly thought of life is strange.

Robert Rodgers says:

Brilliant Video! I love this summary. Thank You!

Robert Andersson says:

3:28 Grace Hopper? Bugs? Grasshopper?
