Who was Harry Nyquist?

Dear Members and constituents,
Ever wonder why a T-1 has 1,536 Kilobits per second of capacity? Why not a round number? Even if you were to use Kilobytes per second you'd come up with 192 KB per second. In case you were wondering, it all comes down to the dawn of digital voice communications. In order to reconstruct a sound, the samples taken can be no less than half of the frequency of the sound we are trying to represent. In normal conversation the human voice seldom exceeds 16 KHz and therefore sampling it 8,000 times per second would be sufficient for both sides to understand each other. They also decided 256 levels (8 bits) per sample provided sufficient information. Of course 8,000 samples per second at 8 bits per sample provide us with 64,000 bits per second, the bandwidth of a phone call. That is, of course, why your voice on a phone conversation sounds a little "tinny" and does not have quite the quality of, say, a CD. You take 24 of these together and, voilà, you have a DS-1.


Lately I have been wondering what the energy capacity of a dozen donuts is and how you would express it. I like the idea of expressing it in Kilobites, however that would probably be a measure of how filling a dozen donuts is, not exactly a measure of energy potential. I'm sure you coud take the mass of each donut and multiply it by the calories per mass unit and then add it up… then again, perhaps some things are better left unquantified. Speaking of quantities, due to their reputation for having a smaller size, Mr. Bagnato has proactively brought in five dozen Krispy Kreme dounts. In looking at the selection he made for this his debut, I think we can expect many good Fridays from Jim.


Happy Friday!

Bring your own Geiger counter!

Friends, This week’s news were literally radioactive -and I’m not talking about the fallout from the Trump-Putin summit. I’m talking mutate your DNA-exciting news. I’m talking Marie Curie-worthy news. I’m talking Geiger-counter-tilting news. I’m talking… well, you get the (glow in the dark) picture. A study about a lone wolf collared near Chernobyl and tracked on a long trek spawned the headline “ Could Chernobyl Wolves Be Spreading Mutations? ” While one can be forgiven for envisioning a flying wolf with laser eyes and a green aura about it, the disappointing story basically says most mutations are harmful to an animal’s health -and unhealthy animals are unlikely to travel 250 miles and mate with other wolves, contaminating the gene pool. So, much ado about nothing. The desire to open Rocky Flats (a nuclear weapons facility turned wildlife refuge) to the public has triggered some litigation from an environmentalist group. At st...

Gilding the Donut

Friends, Despite writing about donuts (sort of) for over 20 years, I don’t believe in sugar coating, after all, honesty is the best policy. Gilding, on the other hand I’m good with. Take the church of the Society of Jesus in Quito, (AKA La Compañía). Built in fits and starts between 1597 and 1765, the volcanic rock baroque facade conceals a spectacular interior. I had the chance to go inside this week and although I had heard about the gold leaf work inside, the descriptions had not done it justice. The details from floor to ceiling transport you to another world, perhaps that’s the point. If you’re ever there, be sure to visit. And while you’re there stop by one of the many panaderías … if you’re lucky they might even have a donut. Happy Friday!

Donut Doodle Dandy

Dear Members and Constituents, In trying to figure-out Wednesday’s cool-looking Google Doodle ( Jorge Luis Borges’ 112 th birthday ), I stumbled across a list of Google Doodles you’ll never see. This, and a Rockies game later that day, were sufficient inspiration to get my head spinning around what other doodles Google might never noodle? I’m sure you’ll probably have a few ideas of your own, but I was able to come-up with a couple. How about a former Colorado Rockies player whose unfortunate encounter with a moth put him in the news this week? The Matt Holliday doodle might look something like this… Another item which, surprisingly enough, has not been made into a doodle are donuts. Although I was slightly taken aback to find this delicious pastry has not been featured, after the initial disappointment, I decided to take matters into my own hands and take a stab at one (perhaps Google can use it next year for national donut day )… or to celebrate Greek police having “ blown a ho...
