 Focus on Producing Information, Not Consuming

The production of information is critical to a healthy information diet. It's the thing that makes it so that your information consumption has purpose. I cannot think of more important advice to give anyone: start your day with a producer mindset, not a consumer mindset. If you begin your day checking the news, checking your email, and checking your notifications, you've launched yourself into a day of grazing a mindless consumption. [...] But there's something else that being a producer do...

 Canons and Fugues

The idea of a canon is that one single theme is played against itself. This is done by having "copies" of the theme played by the various participating voices. But there are means' ways to do this. The most straightforward of all canons is the round, such as "Three Blind Mice", "Row, Row, Row Your Boat", or " Frere Jacques". Here, the theme enters in the first voice and, after a fixed time-delay, a "copy" of it enters, in precisely the same key. After the same fixed time-delay in the second v...

 NPCs in the Game "Real Life"

The NPCs have no depth. The can only carry on brief repetitive conversations about simple topics, such as the weather or football. They all follow simple repetitive paths from home, to work, to the store, and back home again where they spend the majority of their time watching television.

 加油 as a Term of Encouragement

The Chinese characters say 加油 (Jia1 you2).加 is composed of 力 (power) and 口 (mouth). It means 'to add'油 is made out of 水 (氵, water) and 由(from/ due). It means oil.加(to add) 油(oil)= add oil or make an extra effort 加油 is a terribly common phrase in day to day life. If you want to encourage someone to carry on great work, or in a sports competition, you say 加油! A bit like 'go on!' in English. Of course another literal meaning of 加油 is to refuel.

 Scientific Progress Crushes Conservativism

Innovations, free thinking is blowing like a storm; those that stand in front of it, ignorant scholars like you, false scientists, perverse conservatives, obstinate goats, resisting mules are being crushed under the weight of these innovations. You are nothing but ants standing in front of the giants; nothing but chicks trying to challenge roaring volcanoes!

 History of Science and Religion

Some people want to put warning stickers on biology textbooks, saying that the theory of evolution is just one of many theories, take it or leave it. Now, religion long predates science; it'll be here forever. That's not the issue. The problem comes when religion enters the science classroom. There's no tradition of scientists knocking down the Sunday school door, telling preachers what to teach. Scientists don't picket churches. By and arge—though it may not look this way today—science a...

 Seeing Farther From the Shoulders of Giants

We are like dwarfs [the moderns] sitting on the shoulders of giants [the ancients]. Our glance can thus take in more things and reach farther than theirs. It is not because our sight is sharper nor our height greater than theirs; it is that we are carried and elevated by the high stature of the giants.

 Earth's Curve, Flat Maps, and the Fastest Route Between T...

Imagine, say, that you wanted to travel from New York to Madrid, two cities that are at almost the same latitude. If the earth were flat, the shortest route would be to head straight east. If you did that, you would arrive in Madrid after traveling 3,707 miles. But due to the earth's curvature, there is a path that on a flat map looks curved and hence longer, but which is actually shorter. You can get there in 3,605 miles if you follow the great-circle route. which is to first head northeast,...

Because the Earth is a sphere and maps are flat, the fastest route between two points on a map is actually a curved line and airlines take this into account when plotting flight paths.

 Program Yourself With the Truth

What memes should you program yourself with, now that you have the chance? The second-most-popular answer (after punting) is: With the truth. It's hard to see how there could be any problem with programming yourself with memes that are true. But remember Alfred North Whitehead: all truths are half-truths. There are several problems with the strategy-meme Program myself with the truth. In the first place, you can't ever know the whole truth of the universe. Your brain doesn't have enough stor...

 An Origami Metaphor for Fetal Development

The sheets of tissue that fold, invaginate and turn inside out in a developing embryo do indeed grow, and it is that very growth that provides part of the motive force which, in origami, is supplied by the human hand. If you wanted to make an origami model with a sheet of living tissue instead of dead paper, there is at least a sporting chance that, if the sheet were to grow in just the right way, not uniformly but faster in some parts of the sheet than in others, this might automatically cau...
