There’s so much more to discover

"Fibonacci numbers and Phi are related to spiral growth" "If you sum the squares of any series of Fibonacci numbers, they will equal the last Fibonacci number used in the series times the next Fibonacci number. This property results in the Fibonacci spiral seen in everything from sea shells to galaxies"

This is what a sonic boom looks like

Nerve ending broken open to show synaptic vesicles

Scanning electron micrograph of rods and cones in the eye. Rods are long nerve cells which respond to dim light, enabling images to be detected. Cones are shorter cells which detect color.

Gravitational waves, much like the recently discovered Higgs boson, are notoriously difficult to observe. Scientists first detected these ripples in the fabric of space-time indirectly, using radio signals from a pulsar-neutron star binary system. The find, which required exquisitely accurate timing of the radio signals, garnered its discoverers a Nobel Prize. Now a team of astronomers has detected the same effect at optical wavelengths, in light from a pair of eclipsing white dwarf stars.

Inner ear hair cells. Coloured scanning electron micrograph (SEM) of sensory hair cells from the inner ear. These cells are surrounded by a fluid called endolymph. As sound enters the ear it causes waves to form in the endolymph, which in turn cause the hairs to move. The movement is converted to an electrical signal that is passed on to the brain. Each crescent-shaped arrangement of hairs lies atop a single cell.

An F/A-18 Hornet was photographed just as it broke the sound barrier. When an airplane travels at a speed faster than sound, density waves of sound emitted by the plane cannot precede the plane, and so accumulate in a cone behind the plane. When this shock wave passes, a listener hears all at once the sound emitted over a longer period: a sonic boom. As a plane accelerates to just break the sound barrier, however, an unusual cloud might form. The origin of this cloud is still debated.

Martin Oeggerli Fibrin is a protein created by the body that works with platelets in the blood to clot a wound. As they reach the wound site, they attach themselves to fibers, and create a mesh. Working with the platelets, they make a scab that covers the wound until it heals. Though, with the naked eye you would never guess that the process looks like this.
