Most Important Invention?

I gotta go with the Thermos. I put something hot in there and it stays hot. I put something cold in there and it stays cold. How in the world does it know?

 

Ditto! it's a great invention we take for granted. The flush toilet, where would the world go without it?

Down the drain!..Wait, it is going there anyway.

London,England, one of the oldest cities in civilization and yet we were without indoor privies long after America was flushing. When we did get plumbing, the open drain used to run beside the house to the street drain. One could pull the chain indoors and run outdoors and watch....Of course, that was before the telly.

How modern are we?

I'd have to go with the transister. It led the way out of vacuum tubes and really made the computer and high tech electronics possible. The world has truly not been the same since.

WW2'er

 

Tube amplifiers are a much better sound tho, WW2er. We have both. Hubby sells both and perfers the tube amps anyday.

It may not be the greatest invention, but it is one often taken for granted--the calculator.

When I was in high school we had to rely on a slide-rule for more advanced calculations.

DHK...a good practitioner with a sliderule can out do any calculator on the market. I grew up with the sliderule also, it is standard equipment for architects and engineers.

I guess as a lady, I have a somewhat different perspective of what I appreciate in modern day convenience. And whoever invented the grocery store where you can buy bread already made, butter already churned, and meat already caught, killed and prepared has my vote too.

 

Being proficient in both slide rule and calculator, I can assure you that my old HP 20S can run circles around anyone on my old Picket Stat Rule.

I'm impressed by slide rule performance, but you just can't get the kind of accuracy a calculator gets with a slide rule.

 

My son has a graphing calculator. He is in grade 10. It comes with a 455 page user's guide. I can't figure it out. But then he can't figure out my slide-rule.

 

Electricity brings good things to life

 

I always thought that graphing calculators were for kids in math class. Then I finally got one.

When one is out in the field, and one puts in the raw data, and a histogram pops up, one begins to appreciate the advantages.

 

Atomic and Nuclear Bombs:

The first ended WW2 and the second ended the Cold War without ever firing a shot.

God Bless Reagan and America...
