Honeybees are not native to North America

Bee skep

Honeybees were brought to America by the early European settlers. At that time, they use skeps, upside down woven bowls to maintain the bee hives.

In the mid 1800s a Presbyterian minister named Lorenzo Langstroth, discovered that the bees built their honeycombs by precise measurements, and incorporated this into the wood frame beehive that is still in use today.

The Nazi Saboteurs in America

Dave — Fri, 25 May 2018 15:54:48 +0000

Several years ago I came across this amazing story on the This American Life program about a bungled Nazi plot of sabotage only six months after Pearl Harbor. When this program first aired, it drew comparisons to present day efforts to try Islamic terrorists in military tribunals. The legal precedent they were siting was the case of these Nazi saboteurs. It’s a great story and well worth a listen. It shows how legal justice is a very complicated thing and is often manipulated to fulfill agendas.
Recently another podcast, Retropod, brought this story up again. A mysterious stone memorial was found in 2006 in Washington, D.C. on government property, a memorial to these Nazi spies.

Are you using “steep learning curve” wrong?

Dave — Wed, 23 May 2018 14:21:42 +0000

Stephen Dubner’s Freakonomics podcast episode pointed out that using the term “steep learning curve” to describe something that is difficult to master is incorrect. I’ve been guilty of this and now notice I’m not the only one. Within a day or so, I heard another person on a different podcast use the term incorrectly.

From the transcript:

Stephen Dubner is interviewing Scott Lilienfeld, a professor of psychology at Emory University.

DUBNER: And the last one weâ€ll do right now is â€œsteep learning curve.â€

LILIENFELD: A lot of people will say, â€œOh, I started on a new job where I was having to do something new. And this job has a really steep learning curve.â€ In fact theyâ€re getting it backward. A steep learning curve is easy. Because a steep learning curve means â€”

DUBNER: You learn a lot in a hurry, right?

LILIENFELD: Not slowly.

DUBNER: When I read that in your paper I thought, â€œOh my goodness, thatâ€s really interesting that weâ€ve all got it backwards.â€ But then I quickly rationalized and said, â€œWell, I guess what I always assumed was that the steepness was on the axis referring to difficulty somehow,â€ right? And that if a task is particularly difficult, then thatâ€s the steepness, and thatâ€s the curve Iâ€m on. So really, when we encounter something thatâ€s really difficult, and weâ€re having a hard time mastering it, we should say weâ€re on a very shallow â€”

LILIENFELD: A very shallow learning curve, thatâ€s right. I think when people say, â€œThis task has a steep learning curve,â€ what they mean is, â€œMan, I feel like Iâ€m going up like Sisyphus pushing the rock up the hill and going up a very steep mountain!â€ But in fact if something has a steep learning curve, that means that itâ€s acquired very quickly.

How One Man Ruined Fast Food French Fries

Dave — Thu, 19 Apr 2018 18:10:14 +0000

Back in the 90s I noticed that all the Fast Food chains started to change their french fries. They seemed to go to this new, tasteless, batter coated version of their former fries. Most noticeably to me, Burger King then Wendys. I could not understand the reason and suspected it had something to do with trying to make them healthier. Well, as Malcolm Gladwell points out in his podcast, it all came about from one man’s misguided crusade. The worst thing about it, is now that some of the ideas behind the change have been debunked, no one seems to be in a rush to bring back the tastier version.

Driverless Cars Still Have a Ways to Go

Dave — Tue, 28 Nov 2017 16:19:46 +0000

I’m looking forward to the day I don’t have to pay attention to driving my car and I’m all too ready to leave the driving to a computer. But, insiders in the engineering of this, caution that the tech still has a lot of ground still to cover. As one engineer in this latest podcast from Gimlet “Startup,” says that you hear a lot of people touting how safer we will be when we give up the control to a computer. In the US we lose over 30,000 lives to vehicle fatalities and most are attributed to driver error. What they don’t tell you, he points out, is that humans currently operate vehicles for 100 million miles for each fatality. That’s a pretty good record and he doesn’t think computers are even close to that yet.

Billiard Balls were made of Ivory up until the 1950s

Dave — Wed, 18 Jan 2017 18:54:05 +0000

According to this excellent 99% Invisible podcast, billiard balls were made of ivory tusk up until they found a suitable replacement in the 1950s. Think it’s easy to make a billiard ball, check out this video of the process.

The 13 Month Calendar

Dave — Mon, 21 Sep 2015 13:12:50 +0000

I love the podcast 99% Invisible, I could probably post almost all of their episodes here on my blog of interesting things I learned. This one, though, really appealed to me. I really liked this idea of reforming the calendar to a 13 month schedule. Every month would have 28 days and each day of the month would correspond to the same number in each month, e.g. the second is always a Monday, the twenty first is always a Saturday. All holidays would be moved to Monday. (Although, I’m very fond of Thanksgiving, since it falls on a Thursday, most offices will take the rest of the week off.) Traditionalists would be appalled, especially the problem with what to do with July 4th holiday. Wikipedia has a page on it listing pros and cons of the calendar, where, I believe, most to the cons are weak (or should that be week). Alas, it’s only a thought experiment, I really don’t think it would ever catch on.

Palm Trees Are Not Actually Trees

Dave — Fri, 20 Mar 2015 15:17:35 +0000

Listening to the podcast 99% Invisible I learned that palm trees are not actually trees. They are kind of a super grass, according to Jared Farmer who wrote Trees in Paradise: A California History. From the podcast, “palm trees don’t make bark or branches. If you cut them down you won’t find any rings in the trunk, all their roots grow in a compact ball…” This is an interesting story about palms in California and how demand has caused some mature trees to sell for as much as $20,000. Also great podcast.”
