 The Magic Circle

The term magic circle is appropriate because there is in fact something genuinely magical that happens when a game begins. A fancy Backgammon set sitting all alone might be a pretty decoration on the coffee table. If this is the function that the game is serving-decoration-it doesn't really matter how the game pieces are arranged, if some of them are out of place, or even missing. However, once you sit down with a friend to play a game of Backgammon, the arrangement of the pieces suddenly bec...

 Roman Arithmetic

...basic Roman arithmetic is largely rather simple, even for those of us spoiled by Arabic notation. Addition is no sweat, because complex Roman numbers already use what math pros call additive notation, with numerals set beside one another to create a larger number. VI is just V plus I, after all. To add large numbers, simply pile all the letters together, arrange them in descending order, and there’s your sum. CLXVI plus CLXVI? CCLLXXVVII, or CCCXXXII. And one of the advantages of the Rom...

 You Need More than Passion to Change the World

You have to go through life with more than just passion for change; you need a strategy. I'll repeat that. I want you to have passion, but you have to have a strategy. Not just awareness, but action. Not just hashtags, but votes. [...] But to bring about structural change, lasting change, awareness is not enough. It requires changes in law, changes in custom. If you care about mass incarceration, let me ask you: How are you pressuring members of Congress to pass the criminal justice ...

 Physiological Decline in the Body When You Stop Exercising

...regular endurance exercise leads to four major consequences: Increased ability of the heart to eject blood increased ability of the blood vessels to send blood to where blood is needed Increased number of capillaries (the vessels that deliver oxygen and ‘food’ to the muscles) increased size and the number of mitochondria (the “power plants” of the cells). All these changes lead to the more efficient use of oxygen, as well as nutrients. [...] Pino considers a person who can run...

 The Chain of Human Rights to Morphological Freedom

The right to life, the right to not have other people prevent oneself from surviving, is a central right, without which all other rights have no meaning. But to realize the right to life we need other rights. Another central right for any humanistic view of human rights is the right to seek happiness. Without it human flourishing is unprotected, and there is not much point in having a freedom to live if it will not be at least a potentially happy life. In a way the right to life follows from...

 Drugs is a Human Construct

The human body is an assembly of chemicals, as is all food & all medicine. So what we label as a drug is a social construct. Lifting weights changes your bio-physiology in a way that creates performance-enhancing effects on your body. Drinking coffee changes your metabolism in a way that creates performance-enhancing effects on your body. Eating breakfast changes your biochemstry in a way that creates performance-enhancing effects on your body. Practicing in your sport of choice creat...

 Science Depends on Revolutions Large and Small

Scientific development depends in part on a process of non-incremental or revolutionary change. Some revolutions are large, like those associated with the names of Copernicus, Newton, or Darwin, but most are much smaller, like the discovery of oxygen or the planet Uranus. The usual prelude to changes of this sort is, I believed, the awareness of anomaly, of an occurrence or set of occurrences that does not fit existing ways of ordering phenomena. The changes that result therefore require 'put...

 The Amount of Energy in the Universe is Constant

The total quantity of all the forces capable of work in the whole universe remains eternal and unchanged throughout all their changes. All change in nature amounts to this, that force can change its form and locality, without its quantity being changed. The universe possesses, once for all, a store of force which is not altered by any change of phenomena, can neither be increased nor diminished, and which maintains any change which takes place on it.

 Ontogeny and Phylogeny

The History of Evolution of Organisms consists of two kindred and closely connected parts: Ontogeny, which is the history of the evolution of individual organisms, and Phylogeny, which is the history of the evolution of organic tribes. Ontogency is a brief and rapid recapitulation of Phylogeny, dependent on the physiological functions of Heredity (reproduction) and Adaptation (nutrition). The individual organism reproduces in the rapid and short course of its own evolution the most important ...

 We See the Momentary End-Point of the State of the Earth

In the course of the history of the earth innumerable events have occurred one after another, causing changes of states, all with certain lasting consequences. This is the basis of our developmental law, which, in a nutshell, claims that the diversity of phenomena is a necessary consequence of the accumulation of the results of all individual occurrences happening one after another... The current state of the earth, thus, constitutes the as yet most diverse final result, which of course repre...
