Arguing with People Online Allows Them to Burn Your Time
But while some amount of bullshit is inevitably forced on you, the bullshit that sneaks into your life by tricking you is no one's fault but your own. And yet the bullshit you choose may be harder to eliminate than the bullshit that's forced on you. Things that lure you into wasting your time on them have to be really good at tricking you. An example that will be familiar to a lot of people is arguing online. When someone contradicts you, they're in a sense attacking you. Sometimes pretty ove...Folksonomies: opportunity cost online debate

Two Views of Consciousness
There is no end of hypotheses about consciousness, particularly by philosophers. But most of these are not what we might call principled scientific theories, based on observables and related to the functions of the brain and body. Several theories of consciousness based on functionalism and on the machine model of the mind... have recently been proposed. These generally come in two flavors: one in which consciousness is assumed to be efficacious, and another in which it is considered an epiph...Folksonomies: consciousness

notesOne view is that it is the executive function of the brain, the other is that it is a byproduct of its processing.

Davy VS Gay-Lussac in the Race to Discover Iodine
He was warmly received by Cuvier, Ampère and Berthollet, but got into an awkward priority dispute with the gifted young chemist Joseph Gay-Lussac. Gay-Lussac, Davy’s exact contemporary, had made a popular name in France with his intrepid ballooning exploits, and had been hard on Davy’s heels with potassium and sodium experiments. Both were now given by the Académie des Sciences a newly isolated substance to analyse: a strange violet crystal recently found as a byproduct of gunpowder man... 1 notes

The Brain Consumes Lactose During Exercise
Scientists have discovered that lactose, a byproduct of intense muscular activities, can be used to fuel the brain with energy. When glucose, the natural fuel of the brain, is no longer present in sufficient quantities, the cell tissue can “switch” to alternative energy, to prevent any damage to the brain on account of the lack of energy.
[...]
Consequently, by consuming the lactose in the blood, the brain clears the way for glucose, the main powering substance in the body, to reach the...

1 This frees up the body's glucose to fuel the muscles in times of high energy demands on the body (Note: This meme must be wrong in using the term "lactose," because that is a sugar that comes from milk. "Lactate" is a byproduct of muscles consuming glucose that fuels the brain while the muscles take energy-precedence).

Lactate, Lactose, and Lactase
Lactate
Lactate is a negatively charged molecule formed from a compound called lactic acid. Some bacteria make lactate when they metabolize sugars. Humans also produce lactate as a byproduct of metabolism, though only under certain conditions. Specifically, says Dr. Gary Thibodeau in his book "Anatomy and Physiology," you make lactate when your cells process sugars for energy in the absence of oxygen, such as when you're engaging in a hard sprint or power efforts during exercise.
Lact...Lactose and Lactase apparently have no relation to Lactate. Lactose is a sugar in milk, Lactase is an enzyme babies use to digest milk, and Lactate is a byproduct of our muscles expending energy, which is itself a source of energy.

Science Tames Nature by Understanding
Man masters nature not by force but by understanding. rhis is why science has succeeded where magic failed: because it has looked for no spell to cast over nature. The alchemist and the magician in the Middle Ages thought, and the addict of comic strips is still encouraged to think, that nature must be mastered by a device which outrages her laws. But in four hundred years since the Scientific Revolu tion we have learned that we gain our ends only with the laws of nature; we control her only ...Contrasted with comics, fiction, and religion, where nature is subdued by force and magic.
