If you live in New York City or many other places, you’ve doubtlessly gotten used to restaurants and bars having no smoke in them. Perhaps, like me, you’ve come to find the idea, or experience, of smoke around you when you eat or drink or in any public space you can’t avoid barbaric. Does “barbaric” overstate things? I used to consider myself tolerant of smoke in bars and clubs. Actually,[…] Keep reading →

We visited North Korea for ten days in April, in part for the hundredth anniversary of Kim Il Sung’s birth. North Korea is amazing. This trip surpassed our first in many ways, as before in ways we could never have predicted and, having experienced it, can’t explain, much as we’d like to. Everyone on the trip agreed, as happened with the first trip. You had to be there to feel[…] Keep reading →

I wrote the following after reading this article from a venture capitalist giving advice to people thinking about starting companies. A lot of advice VCs give entrepreneurs seems to me versions of “make my job easier,” like how to write a great business plan, how to pitch, etc. In this case, I see him asking entrepreneurs to improve the signal-to-noise ratio so he can have an easier time funding companies.[…] Keep reading →

Following up yesterday’s post on balance sheets and charts for using and producing energy and reporting our numbers to see if we can make them balance, let’s look at carbon flows. People who don’t know about carbon emissions, flows, and balance confuse simple ideas with each other. For example, some talk about how volcanoes and cows digestive systems produce tons of carbon and wonder why we should bother changing our[…] Keep reading →

People don’t realize it, but business people have some of the best the skills to understand our effect on the environment. We should learn those skills from them. I didn’t have much (any?) business experience when I co-founded my first company. I couldn’t read a balance sheet or know accounting. My science background taught me to understand general and broad patterns, which don’t suffice for running a company. Either the[…] Keep reading →

Imagine living your whole life nearsighted and one day you wear glasses for the first time — everything going from fuzzy blobs to clear. Or you know after you get out of the pool and your ears have water in them? Imagine you heard like that for your whole life and suddenly they cleared and you could hear properly. Or you’ve been wearing gloves and for the first time you[…] Keep reading →

The major “Communist” countries my country invaded or fought during the Cold War without doing so well — I just visited (or smoked a cigar from). It gives you the opportunity to learn. The dominant voices in the United States, especially during an election year, cheer that we’re number one. You hardly hear anything else. I can’t imaging a politician disagreeing in the slightest having a hope of election. Seeing[…] Keep reading →

A culture’s food tells you its values — some of its most important ones. I just had fresh squeezed mango and some mangosteens on the streets of Ho Chi Minh City. They cost almost nothing here. They were as delicious as any fruit I’ve eaten. Two weeks ago I could barely put another oil soaked vegetable in my mouth in North Korea. We had little choice in where or what[…] Keep reading →

Math and science to me are beautiful — about the most beautiful things in the world. I hope some of that comes across when I write on them. After a couple posts on a physicist’s perspective on our impact on the world — about an awesome blog (called Do The Math, but it has a science perspective) and an awesome video presentation by the blogger, here’s something on math. When[…] Keep reading →
