I'm still thinking back to 20 no, 30 years ago now, omigod longer--to my high school days--and we had COMPUTER DANCES
--Girl student would fill out a very long questionnaire with questions about your personality and likes and dislikes with a "number 2 pencil", remembering to fill in all of the little circle correctly, and then Boy student would fill out a different very long questionnaire etcetera with his answers and then the answer sheets would go into a very large "machine" and voila,
out pops a sheet with the boy or girl of your dreams. One who just happened to be at said Computer Dance. Not my dreams, though, in 1970.

Next weekend is my 30th college reunion (yikes) and I was positively delighted that my class was the last that did not have to take the mandatory computer class. Who ever needed to know about computers?????

The problem with energy conversion from one form to another is that you are always going to loose part of it in the form of heat. So even if there were a process that allowed you to convert energy at 100% efficiency, you are still going to lose some it due to friction between moving parts, for example.

Hybrids have an overall efficiency higher than gasoline only vehicles because they recover a (small) fraction of energy during braking, and don't run while stopped. Hybrids are a step in the right direction, but they still have a long way to go.

I now have an excuse for why I run so slowly....think BAYWATCH slow-mo, but only with a guy and the focus is a bit lower, on the ol' gut. Now, put a shirt over that and the rubbing of gut and garment create heat which is obvioulsy going to slow me down due to loss of energy as everyone has explained quite clearly. The only solution, as I see it, is for me to remove all clothing at all future Fun Runs. YOUR science will make me a better runner!! Thank you!

(gotwood, take it home with an apropos pic.......)

No fair taking me back to college days when computers were the size of buildings and spindle/punch cards were used to sort for statistical information. I can still remember key entry of data into the computer and the punched cards we had to sort to prove our hypothesis, etc. This looks exactly like the reader we had at UCR circa 1970...


I much prefer the modern technology of smaller accessories

Flash drives come in various, sometimes bulky or novelty, shapes and sizes, in this case ikura sushi

I spent 15 years as an IBM Customer Engineer (on site technician) in their Office Products division beginning in the 60's.. I serviced the first word processors that stored information on a magnetic tape. Today's tiny flash drives will store more information than a closet full of MT/ST tapes.

The technology advancements we have made over the past 40 boggles the mind.

FBM - I took a "Business Machines" class in HS where key punch was one of the skills we learned... for whatever good it did me!

When I was very young (before my current career) I was a secretary for several years. I felt like queen of the office when I was the first to receive an IBM Selectric III... had correction tape built in and everything! Just had to backspace, type the error and it would lift it right off the page... thought nothing could beat it!!!
lafmom ...

Aw yes ... the Selectric. Couldn't live without it but it was a pain in the patootie if you had to make (remember these) CARBON COPIES !!!

I also had the use of an old telex machine ...

We communicated with Australia all the time and because of the time difference, we spent the last hour of the day sending telexes. One afternoon, we had to stop during the middle of a last minute 'office party' to send the telexes, so I took my Harvey Wallbanger into the little room with me and proceeded to spill the da*n thing on the keyboard of my telex machine. What a mess. Had to have a technician come out the next day and clean it up and unstick several keys. That was the last time I set my drink on the telex machine ... I just started using the Xerox machine next to it

Oh, the days when I would decide to pull out fresh carbon paper and pitch the almost transparents pieces! Big Grin Woe is me though, when you pulled out your typed pieces and all those carbons behind it and found an error.... could take ya a half a day to try and align everything up!! Eek
Thanks for the bump, puma --- however did I miss this the first time around?

The smell of mimeo'd sheets, computer dances (do not bend, fold, spindle, or mutilate --- hey, do you think that eHarmony guy got his start at a Computer Dance?), sorters in the principal's office (all the little punched-out rectangles made for great game day confetti), temperature controlled computer rooms....

FBM, we used telexes in the travel business; I still think of them as twx, and passengers as pax. Some twxes were so full of telexspeak that you'd need a Rosetta Stone to decipher.

So, Fungo, a fellow Beemer? I sold for the Office Products division for a few years in the early '70's. WP, selectrics, Executives, copiers.....and dictation equipment. Surely you remember the "portable" version that was roughly the size of a hardback book. (Ah, when you sold one of those systems, you knew how to sell!)

Our techs used to complain of all coffee and french fries they found in the equipment....your office sounds a lot more fun, FBM!

And who does know what wonders await over the next few years. Or maybe we'll hit a plateau. I mean, where are those blasted Jet Packs we were promised? Or the Paperless Office IBM talked about 35 years ago?

A few years back, a 111 year old Welshman was being interviewed and was asked what was the most important, life-changing invention in his lifetime. The interviewer expected to hear him cite the telephone, the widespread use of cars, photography, and motion pictures, maybe air travel or the computer, even space flight.

Nope.

It was Tarmacadam. Paved Roads. He said you can't imagine life when the roads were all dirt, the mess, the filth, carried into the house the cleaning it took, the health issues. Interesting how the most commonplace thing was also the most important.
