Title: How advanced iş the latest/current technology?
Post by: SoldierofFortune on May 09, 2021, 02:12:45 PM
I do not talk about what is made known publicly, instead I want to learn how far they have gone, in their monopolistic area of science and technology. I may not understand but give me some rough idea.

Please dont claim the Iphone 12 as the most advanced :d

I remember "Duck Dodgers in the twenty-fifth and a half century!"

You can buy vacuum tube audio amplifiers with LED lights now.

Even though vacuum tubes are no longer used, I still can't understand how they work.  It was like screwing a bunch of light bulbs into a socket strip and expecting something special to happen.

They were switching units IIRC.

"The basic working principle of a vacuum tube is a phenomenon called thermionic emission. It works like this: you heat up a metal, and the thermal energy knocks some electrons loose. ... When the cathode is heated, and a positive voltage is applied to the anode, electrons can flow from the cathode to the anode. Jan 18, 2018"

That was fun.  It's at a level I understand.

Even though we are told we cannot transport things through space, we have in fact done it.....I saw it on TV.

There's a quip in Bill Bryson's, A Short History of Nearly Everything, that goes, "The next time you complain about nothing to watch on TV, turn to one of the channels that isn't broadcasting anything and watch those little jittery dots for awhile.  You will be watching the back ground microwave radiation left over from the Big Bang.  What we call the "snow" on a blank TV screen has traveled 13.7 billion light years through space to bring you the moment of creation.

He takes longer to explain, but most people here don't need that.  I added the part about 13.7 billion light years.  I don't know if all of it comes from that far away.  I just assumed that, because it makes me feel smart.

The VA doctors put that down as my official diagnosis.

Current technology?  Let me tell you.   It is more advanced than yesterday, but not as advanced as it will be tomorrow.

Looking further away = looking back further in time.  So it is indeed from that far away.
