Einstein’s theory of relativity on display for first time
In a darkened room in Jerusalem, the world was given a rare glimpse Sunday into the mind of Albert Einstein as he worked to unlock the secrets of the universe.
The display of 46 pages, each handwritten by the famed scientist, marks the first time the complete, original manuscript of his landmark “General Theory of Relativity” has been presented in public.
“I create thin metal films that can be reversibly stretched and remain conductive. PDMS serves as our platform/substrate. PDMS is Polydimethylsiloxane a elastomeric polymer and after being reversibly stretched, comes back to its origninal size and form. These thin-metal films provide a platform for the realization of stretchable electronic circuits. We cast the PDMS into petri dishes by mixing the liquid polymer with a curing agent and after stirring, the mixture is cured for 24 hours at 70 degree Celsius. This photograph shows a multilayer of silicone elastomer (PDMS)/gold/PDMS. The image was taken by optical microscope. There are no manipulations or enhancements to the photograph.” source
Today’s Poison: Cyanide!
Cyanide can naturally occur in very small concentrations in the pits of some fruits, but is commonly manufactured by blending Ammonia with Hydrogen and Carbon. The cyanide anion is an inhibitor of a key enzyme in the electron transport chain (found in the membrane of the mitochondria of eukaryotic cells). As a result, the electron transport chain is disrupted, meaning that the cell can no longer aerobically produce ATP for energy. Tissues that mainly depend on aerobic respiration, such as the central nervous system and the heart, are particularly affected.
