At 18, Katie Stubblefield lost her face. At 21, she became the youngest person in the U.S. to undergo the still experimental surgery. Follow her incredible story.
If earthquake happened, firstly, don’t panic and calm down. Secondly, find some safe place to stay and don‘t run in such a hurry. If in the room, one should hide himself/herself under something hard, such as desk, table or even bed and keep away from shelf and cupboard, and never...
Plants exhibit tropisms, tendencies to grow in certain ways based on environmental factors, such as sunlight (phototropism), water (hydrotropism), gravity (gravitropism), chemicals (chemotropism) and even physical contact (thigmotropism). For example, plants tend to bend toward sunlight because sunli...
Einstein's General Theory of Relativity predicted that gravity could bend space. This was later confirmed during a solar eclipse when a star's position was measured before, during and after the eclipse. The star's position shifted because the light from the star was bent by the sun's gravity...
How to Build a Wood Sailboat: I've been wanting to combine my two favorite hobbies - woodworking and sailing for a long time, so I thought I'd build a boat. It's got classic lines and looks so dazzling in the sunshine that people constantly stop me at t
Its a small lawn tractor battery, and the ONLY place it would fit was right behind the engine. I welded two angle iron pieces pointing upwards to form a bracket in which the battery sits. The space is TIGHT. This actually works really well because it moves the center of gravity to the...
Light sometimes acts as a wave and sometimes also acts as a particle or ray. The phenomenon of having these two characteristics is called the wave-particle duality of light. In the Answer and Explanation section, we will give two examples showing the evidence of such special traits....
McKenzie Stommen: It gave … a sense of gravity to what we were doing that these cases have gone unsolved for that long. Around the same time the students began crunching data, Christensen decided it was time for a Hail Mary pass. Colleen Fitzpatrick is the president and fou...
So, if dark matter is effectively "invisible," how can scientists map it? And how do we even know dark matter exists? Put simply, to detect dark matter, astronomers look at its indirect effects on gravity and how it impacts other objects with mass and light. ...
What if the hallway has a bend in it? You could place a mirror at the bend to reflect the light beam around the corner. What if the hallway is very winding with multiple bends? You might line the walls with mirrors and angle the beam so that it bounces from side-to-side all along...
