Rating: 4.0; Vote: 1
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

Simply amazing content! Thank you for all your hard work putting this information and these videos together, much appreciated! I'm from Latvia (post-Soviet country) and my first computer was Windows95, my family got it probably around end of 90's and we were the first ones to get it in around my area. Never knew computers were already there long before that!

The world-s first electronic digital computer was invented by John Vincent Atanasoff in the 1930s at Iowa State University (previously called Iowa State College. Please look up the court case Honeywell v. Sperry Rand.

Bugs were called bugs way before the Grace Hopper incident though: D She just kind of popularized it because the term was well known and it was funny that they found an -actual bug- in the system

7: 02 Now that I think about it, watching this video in 4k might've used as much (if not more) compute as ENIAC in its entire lifetime!
We've come really far

If an average sheet of paper is 100, 000 nanometers thick, and a transistor is 50 nanometers thick. how on earth do you even see the thing let alone make it?

The jump from vacuum tubes to transistors is insanely huge. I had no idea how important the speed of switching power on and off is to computing.

I find it funny that Grace Hopper coined the term computer bug when his entire name is literally 2 letters off from the name of a bug. [Grass Hopper].

-Today computers use transistors that are less that 50nm in size-. when was this video made? Oh, 3 years ago. They're down to 5-14nm now.

I wish I concentrated on my electric electives-, this seems interesting how transition into Transistor playing a vital role in computation.

So, today's semiconductors are 2000 smaller than thick of paper? And they are 100 times faster than any other semiconductor before?
