Common Compound Library A searchable database of over 800 common compound names, formulas, structures, and properties. Companion Notes Hyperlinked notes and guides for first semester general chemistry. Construction Kits Flash-based kits for building chemical formulas, names, equations, and problem solutions.
Andrew Maynard is a scientist and emerging technology adviser. He blogs at 2020 Science and tweets as @2020science . Some of the most entertaining, informative and mind-blowing science videos on the web come from TED – the Technology, Entertainment, Design conference. Challenged to give the “talk of their lives,” the world’s top scientists and science communicators have been dazzling audiences – many of whom are thought leaders, trend-setters and entertainers - for years now.
The Timeline is a visual exploration of key events in the history of science with particular emphasis on chemistry created by artist Murray Robertson.
A lune is a plane figure bounded by two circular arcs of unequal radii , i.e., a crescent. (By contrast, a plane figure bounded by two circular arcs of equal radius is known as a lens .)

Nice to see the Oscillating Universe Theory finally gaining some ground. This was published over a decade ago and has been backed up with echoes from deep space that would have to have been generated before the Big Bang. When you consider that there are more galaxies than stars in the Milky Way you know you'll never see far enough into space to get a glimpse of scale of the universe.
Introductory Quotes to David Bohm's Holographic Universe
Recent discoveries require us to rethink our understanding of history. "The histories of the universe," said renowned physicist Stephen Hawking "depend on what is being measured, contrary to the usual idea that the universe has an objective observer-independent history." Is it possible we live and die in a world of illusions?

Scientists have figured out how stress experienced early in life can cause long-lasting changes in physiology and behavior -- via epigenetics. Image: Max-Planck Institute of Psychiatry, MunichSpecifically, early stress appears to induce epigenetic changes in a specific regulatory region of the genome, affecting the expression of a hormone important in controlling mood and cognition into adulthood, according to a study published online today (November 8) in Nature Neuroscience. This is the fi

The quantum wizardry appears to occur in each of a photosynthetic cell’s millions of antenna proteins. These route energy from electrons spinning in photon-sensitive molecules to nearby reaction-center proteins, which convert it to cell-driving charges.
