Ralph Waldo Emerson once observed that "the seed of science" was "wonder," and taking a look at this nine-layer liquid tower from Steve Spangler's Sick Science! channel, one can't help but do just that — wonder. How is this possible? Is this magic or what?
Because of Android's massive array of supported smartphones that carry vastly different display sizes and resolutions, the operating system uses a value known as DPI to determine the size of icons and visual assets that will best suit a given screen.
There are at least 24,000 different Android devices, and they all have varying hardware components. This is why many developers publish several unique variants of their apps, which, among other things, helps accommodate all of the different display sizes and resolutions on Android phones and tablets.
Ever wonder why Jupiter has those colored bands across its surface? Jupiter's enormous mass is made from an array of different liquids, and those fluids do not play well together because of their different makeup. All of the hydrogen- and helium-based fluids are thought not to be miscible, which means that they aren't homogeneous in nature, resulting in strikingly beautiful bands across the planet's surface. But what about viscosity and how that correlates to the development of planets? What ...

Density is a means of representing how much mass is contained in the body of an object. The basic formula is: Density (D) = Mass (M) / Volume (V) so D=M/V. Density is important to know for buoyancy and to understand how heavy an object is. This video will show you three examples of measuring density so you can learn and put it to good use.
In this episode of Science Theater Dr. Carlson helps you understand the concept behind Density and how it relates to Mass and volume and how to calculate the Density of a substance if its Mass and Volume are known. The Density of various metals is demonstrated using aluminum, tin, zinc, lead and copper of the same mass but different sizes. The easiest way to measure the density of a substance is also mentioned. Next, Dr. Carlson measures his own density using a scale and a bathtub.

To find out the density of any given object there is a simple equation, mass divided by the volume equals the density. In this video a lady is showing how to get the volume of three objects using water. First the objects are measured on a scale to find out how much they weigh, the mass. Next each one of the objects is placed into a measured amount of water to find out the volume. Before you place the object into the water you will want to know just how much water in there. That way when the o...

Photography is a fast growing hobby with the relative drop in prices of high grade equipment. The use of different filters in photography is a very common thing, and different filters have very different uses. The neutral density (ND) filter reduces the amount of light reaching the film or sensor. This allows the photographer to create different effects with the available light, allowing slower shutter speeds and larger apertures. The video helps explain the differences in shutter speeds and ...

A common problem when shooting in low-light situations is that even if you open your lens to its lowest f-stop number, you're left with an image that's far too dark. One obvious remedy is to add more light. But what if you don't have more lights available to you? That's where the gain increase switch comes in. This free video cinematographer's guide will show you how to use digital gain settings to amplify available light to get better shots in less-than-ideal environments.
