It's COLD this morning!

My Dad had a slide rule. He was mechanical engineer - MIT Class of '43. Taught me to use it, and I did a little in high school. Show one to a kid nowadays, they have no idea whatsoever what it is. I think I still have one kicking around in the basement somewhere.

Yup........ still got mine. We had to use them when I was at college studying electrical engineering in the mid '60s. I remember the first calculators. We weren't allowed to use them in the examinations. Size of a brick & they took four AA batteries. Got one now, the size of a credit card, & it's got a tiny solar cell, so you don't need batteries.

BTW it's around 26ºC (82ºF) here today. Went down to the potato warehouse for a sack of potatoes, in a tee shirt, & was sweating when I got back. And the tomato plants on my patio are just coming into flower, so by next month I should have a good crop before it turns wet & cool. :whistle:

Broke a record in the Austin area, 45f this morning.

Decades ago a friend bought one of the first calculators with 4 functions "AND" a memory. $400 was the cost. Almost 4 months rent for me, sheesh.

I always use 20C = 68F as a reference, as that was the temp all the fluids had to be at to process black and white film and photos, back when people did that. From there, every change of 9 degrees F = a change of 5 degrees C. So 77=25, 86=30 and so on.

Wow, you remember those chemical temperatures ???
Once upon a time, there were dark rooms where people are sitting under RED lights.. ha ha ha.
I'm missing those alot...smells of fixer...^^;
Thanks for remind me memories.

I dabbled a little in developing my black and white film many years ago; but I much prefer the ease of digital.

For me it's been 37C = 98.6F (body temp). We all have our peculiarities and different reference points.

For the past 5 years my reference points are: Too cold to ride or too hot to ride. Cage time.

Parked by GZ for the season tonight. :sad: I took it to work every day this week to squeeze in some saddle time before the rains hit and had some GREAT afternoon rides home. But, going TO work? How about 32km at 7C in thick fog? I detoured from my regular route on Tuesday to avoid a known fog bank and got lost in another! My jacket, vest, and shell kept the cold at bay but my hands simply froze. I would get heated gloves or grips if I really wanted to ride in this weather, but it's not my thing. Maybe I'll get them for a x-country trip.
Anyway, it's been a great 1st season of riding!

Cheers!
