At a council in Constance between 1414 and 1417, the man who called himself Pope John XXIII and is now known as Antipope John XXIII (1410–1415; not to be confused with Pope John XXIII, pope from 1958–1963) was convicted of piracy, murder, rape, and incest — and only received three years in prison.
Mary, Mary, quite contrary, how does your nanogarden grow?
Harvard engineer Wim Noorduin has a green thumb. Only his thumb is only a few microns wide. By carefully controlling gradients of chemicals, he guided the construction of flower-like crystal structures to match their larger biological forms. It’s certainly art, but it also demonstrates a masterful manipulation of chemistry on the nano scale.
Just how small are they? As NPR reports, these flowers could fit in the lapel of the tiny Abraham Lincoln statue on the back of a penny (back when pennies had the Lincoln Memorial on them, anyway). These electron microscope images are false colored to recreate fantastic flowers, and these manipulations will one day help control the construction of useful microstructures.
If you’re seriously engineering-inclined, here’s the original research as it appears in Science.
On its own, it is a wonder, but viewed in isolation its complexity and very existence is inexplicable. Darwin’s genius was to see that the existence of something as magnificent as a blade of grass can be understood, but only in the context of its interaction with other living things and, crucially, its evolutionary history. A physicist might say it is a four-dimensional structure, with both spatial and temporal extent, and it is simply impossible to comprehend the existence of such a structure in a universe governed by the simple laws of physics if its history is ignored.
And whilst you are contemplating the humble majesty of a blade of grass, with a spatial extent of a few centimeters but stretching back in the temporal direction for almost a third of the age of the Universe, pause for a moment to consider the viewer, because what is true of the blade of grass is also true fro you. You share the same basic biochemistry, all the way down to the detail of proton waterfalls, and ATP, and much of the same genetic history, carefully documented in your DNA. This is because you share the same common ancestor. You are all related. You were once the same.

Brian Cox channels Richard Feynman in this reminder that viewing science through any single lens is an incomplete view of its magnificence. In other words, physics is beautiful, but it’s a periscope view of life’s majesty.

Meet Mr. Camouflage, one of the special stars of sea life in the Lembeh Strait. I literally said “Whaaaaaaaat the f…” when I saw that amazing color change.
Isn’t evolution grand?

What is Evolution?
Excellent video from Stated Clearly explaining just what evolution is … using great illustrations from Rosemary Mosco’s Bird and Moon comics.
This is a great video to share with friends/enemies/confused relatives that might have trouble accepting evolution and how simple it can be to understand.
I’d like to add one thing to this video. Single amoebas, pairs of parents and a few children are used in these evolution illustrations to simplify the concept of evolution, but it’s important to remember that evolution is something that happens to populations, not individuals. The changes within a generation are random. It’s only after those changes have been passed on for several generations that a survival advantage or disadvantage (followed by either more or less individuals carrying the trait) occurs. That’s where evolution happens, it’s not in the change itself. And sometimes even harmful traits can become frequent in a population, like we see in diseases that are prevalent among isolated ethnic groups.
Bonus: I’d also recommend Understanding Evolution’s “Common Misconceptions” FAQ for those who want to dig deeper.
have you ever discovered a book so good that you’re convinced nobody’s life will be complete until they read it but you also don’t want anyone else to discover it because it’s yours
Most of Virginia Woolf’s work. I barely ever push it on to others or describe it in detail in the fear that I may lose or waste a part of her. I haven’t yet found another person who has experienced what I have upon discovering her.
