Including Images within a Sound file

When it comes to recording information, multimedia files have the obvious upper hand over plain text documents. They have a solid flow with a lot of accompanying data in addition to the objective information. For example, It's much interesting to listen to a narrative as opposed to reading the same information on text form. It's not quite the same. But it is difficult to move at our own pace through an audio unlike text or an image. This can be a headache when it comes to keeping track of contents in long audio/video tracks. Let's look at a couple of features we can make use of to make life easier.

Uses of the Moon and Possibilities

The Earth have one natural satellite; the Moon. The moon is the closest natural celestial body seen to the naked eye from Earth. Scientists believe it has helped shaped life and climate of the planet over the eons. But is there really any use of it? If so, how can we make use of it? Let's look into some possibilities..

How Energy from the Sun Drives the Earth

The Sun produces massive amounts of energy by a process called nuclear fusion where Hydrogen atoms are combined to form Helium atoms. This energy is emitted to space in the form of electromagnetic radiation. After 8 minutes of journey, a portion of it arrives on Earth with an estimated energy density over a 1000 Watts per square meter. About 30% of this energy is reflected back to space. The rest of it powers up the planet as we know it. On Earth, energy arrives in the form of electromagnetic waves including Infra-red (IR), visible light and Ultraviolet (UV). We refer to it as “ sunlight ”. The following list is a composition of the main forms of energies produced from solar energy and stored on Earth.

Strangeness of Colour and its Implications

Our eyes perceive light. Our brains interpret it into shapes and forms that we are familiar with. What we see is lighter or darker depending on how much of light enters the eye (that is; intensity) and is applied with "colours" based on the flavours of light we receive. As vivid as they may be, these so called flavours of light are physically non-existent in nature. They are solely an interpretation that exists only within our perception.

Motions of Gas Molecules: Sound, Wind and Heat

There are 3 distinct states of matter: solid, liquid and gas. The molecular differences between these states are determined by the ability of their kinetic energies to overcome the forces of attraction among the molecules. Out of them, Gaseous state of matter exhibits the highest degree of freedom for movement in 3 dimensional space. This allows gases not only to acquire the shape of the container but also to adapt its volume to occupy the container as well. Interestingly, these moving gas molecules are responsible for three major phenomena distinct from each other.

Plants Growing at Water's Edge

Have you ever wondered why plants and trees growing at the margins of pools and lakes of water look magically beautiful? They grow branches and leaves towards the water. They grow along and across the water surface but never touch it. How is that even possible? Let's look at the processes involved in plants to produce this eye-catching scenery.
