How Do Lasers Work?
Almost all of us are acquainted with lasers, as we have used or seen lasers in action at some point of our lives. Lasers are used in a variety of places, like for pointers for a presentation in a corporate boardroom classroom or as a cat toy.
A closer example at home is the usage […]
Wind Energy: Effective And Efficient Alternative Power Source
Though it is much less expensive to initially get subscriptions into the local electric company’s grid than it is to set up and hook into wind turbines, in the long run one saves money by using the wind for one’s energy needs while also becoming more independent. Not receiving an electric bill while enjoying the […]
Things To Learn About Heat In Physics
Heat is often defined as energy in transit or the the flow of energy. Thermal energy is the energy itself. Heat is also transferred through gases by convection. It is by this means, in part, that a stove or a radiator heats a room. Heat is the number one weather-related killer. On average, more than […]
Milky Way A Changing Galaxy
What comes to your mind when you think of the Milky Way? Well, the Milky Way is a galaxy among the billions of galaxies in the universe. A galaxy refers to a cluster of billions of stars and other heavenly bodies, including solar systems like ours.
Galaxies are classified on the basis of the arrangement […]
How To Get Started In Backyard Astronomy
Often we will see and hear about telescopes, and have a preconceived notion that a telescope is essential to be able to do backyard astronomy, however this is not the case. Nor is it essential to spend hundreds if not thousands of dollars to get started in backyard astronomy as a hobby.
It is true that […]
Harnessing Wind Power: Viable And Effective
With the cost (and pollution levels) of traditional energy sources such as burning coal and other combustible resources being extremely high, countries are obliged by themselves to look at other, more renewable energy sources to meet their needs. Energy from the wind is cited to solve this current energy shortage trends. To get energy from […]
Thermodynamics In Physics And Our Environment
Thermodynamics is the field of physics that describes and correlates the physical properties of macroscopic systems of matter and energy by relating such qualities temperature, pressure, and volume. It also takes in energy, heat, and work. Thermodynamics was founded between 1850 and 1860 by R.W. Joule about the quantitative equivalence between mechanical work and heat.
Thermodynamics […]
