A&[Internet Encyclopedia of Philosophy] An Essay by Einstein. "How strange is the lot of us mortals!
Each of us is here for a brief sojourn; for what purpose he knows not, though he sometimes thinks he senses it. But without deeper reflection one knows from daily life that one exists for other people -- first of all for those upon whose smiles and well-being our own happiness is wholly dependent, and then for the many, unknown to us, to whose destinies we are bound by the ties of sympathy. A hundred times every day I remind myself that my inner and outer life are based on the labors of other men, living and dead, and that I must exert myself in order to give in the same measure as I have received and am still receiving...
"I have never looked upon ease and happiness as ends in themselves -- this critical basis I call the ideal of a pigsty. The ideals that have lighted my way, and time after time have given me new courage to face life cheerfully, have been Kindness, Beauty, and Truth. "My political ideal is democracy. Understanding Your High -The Effects Of Marijuana On Consciousness - 420 Magazine™ A marijuana high usually lasts two or three hours, during which a wide range of effects may occur, varying both in intensity and quality.
The usual, most noticeable effect is intensification of sensation and increased clarity of perception. Visually, COLOURS are brighter, scenes have more depth, patterns are more evident, and figure-ground relations both more distinct and more easily reversible. Other sense modalities do not have the variety of visual stimuli, but all seem to be intensified. Sounds become more distinct, with the user aware of sounds he otherwise might not have noticed. Music, recorded and live, is heard with increased fidelity and dimension, as though there were less distance between the source and the listener. EXPECTANCIES Both the intensification of sensory experience and the expansion of time are part of an increased attentiveness to immediate experience in contrast to memories of the past or plans for the future.

In a previous video, we argued that typical notions of 'something' and 'nothing' don't really make sense according to modern physics. But many commenters objected to this idea, calling it a semantic game. Surely there must be such a thing as a true void: no matter, no energy, no distance... just pure nothingness. In our latest animated explainer, we pick up where we left off and look at whether true nothingness is possible according to physics. You can find out more about the void in our full-length feature: Nothingness: The turbulent life of empty space.

I was going to talk about a cool recent paper that described the evolution of novelties by way of modifying modular gene networks, but I started scribbling it up and realized that I was constantly backtracking to explain some fundamental concepts, so I stopped.
I was concerned because one of the most common sources of confusion I’ve found in my students in the past was difficulty in distinguishing phenotypes from the complexities of the underlying genotype, and I have to be slow and thorough in setting up those differences early on until it sinks in, a habit I’m continuing here. It’s so easy for students to reify a trait, like eye color, into a single discrete property that must be somewhere on a chromosome. It’s not. It’s so much messier than that. Let’s talk about eye color in flies. For example, the specific color of the eye is the product of mixing two pigments, drosopterin and xanthommatin, in appropriate proportions in the pigment cells of the eye.
