The arrow of time is the "one-way direction" or "asymmetry" of time. The thermodynamic arrow of time is provided by the second law of thermodynamics, which says that in an isolated system, entropy tends to increase with time. Entropy can be thought of as a measure of microscopic disorder; thus the second law implies that time is asymmetrical ...
Image credits: Sasha Weilbaker #4 Wind Blades. Humpback Whales are one of the largest weighing animals of the world, yet they are profound swimmers, which attributes down to its flippers (fins).
However four-year-olds and three-year-olds struggled, although four-year-olds were significantly better at identifying animal actions than three-year-olds. This suggests that our perception and understanding of biological motion and actions goes through developmental process in human children, arriving at a performance ceiling for identifying ...
This figure shows nerve activity associated with rotational-induced physiologic nystagmus and spontaneous nystagmus resulting from a lesion of one labyrinth. Thin straight arrows show direction of slow components, thick straight arrows show direction of fast components, and curved arrows show direction of endolymph flow in the horizontal semicircular canals.
The original March of Progress illustration from Early Man (1965) with spread extended (top) and folded (bottom). The March of Progress, [1] [2] [3] originally titled The Road to Homo Sapiens, is an illustration that presents 25 million years of human evolution.
The visual system is the physiological basis of visual perception (the ability to detect and process light).The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment.
Earth’s inner core, a red-hot ball of iron 1,800 miles below our feet, stopped spinning recently, and it may now be reversing directions, according to an analysis of seismic activity.
Sonic 2 came out the following year. Jackson was smitten. And so, late one afternoon, Roger Hector got a call: Jackson would be coming to visit Sega. "He wanted to drop by and say hello," Hector recalls. "There was no agenda beyond it other than, he really, really liked the game. He enjoyed playing it a lot and he wanted to meet the people ...
