  • Wind Turbine Physics: Factors Affecting Performance
    By: Niraj Patel | - The efficiency of wind turbines depends on various factors such as location, geographical factors, mechanics, rotor shape/ size, etc. Output can be regulated by a constant or variable rotational speed, as well as adjustable and non-adjustable blades.


    Power in the Wind

    The importance of accurate wind speed data becomes clear when one understands how the speed affects the power. Consider a disk of area A with an air mass dm flowing through that area. In a time dt ...

  • Things That Can Go Wrong During Exam Day
    By: George Li | - Are you scared that on the morning of your HSC trials or actual HSC exam, something might happen that would affect your ability to do the exam? It is not too bad if something's serious enough to warrant an illness / misadventure claim. For example, if your train breaks down and it's verifiable over the news, or you're unable to attend due to some illness that can be documented by a medical certificate.

    But what about the little things that won't quite warrant a misadventure claim?

  • The Use Of Physics To Improve Your Golf Swing.
    By: Gregg Montgomery | - We all know the golf swing can be a funny old thing, well mine can be at least. You know what I mean, no two shots have the same result even on the range where everything should be near enough constant.

    Why is this? Yes your stance may vary a little from shot to shot, your wrist may brake a little early or late but the main reason for all the variations is the one thing we cannot change though we can try to control to a degree if we understand it.

    And the answer to that ...

  • Science Teacher Resources: Things Many Science Teachers Can't Live Without
    By: Christopher Cameron | - Science teachers have resources that they use all the time for teaching their students and also for educating themselves on certain scientific subjects. A science teacher will often be required to know far more about the subject matter that they are teaching than the students who are being taught. This makes them more effective, by having a complete understanding of their subjects. This also allows them to answer almost any questions that their students may have. These teacher resources are ofte ...

  • Magnetism: Something Fun For Children To Learn
    By: Christopher Cameron | - Magnetism is a scientific term that basically states that materials exert an attractive or repulsive force on other materials. Every object is made up of atoms, and because of that, they all have a charge that causes other objects to be attracted or repulsed. This fact doesn't always seem to be apparent. For example, the computer screen you are viewing right now doesn't seem to be pushing you away or trying to pull you in. That said, many objects have such a slight pull that it is nearly impossi ...

  • The Basics Of Electrostatics
    By: Christopher Cameron | - The branch of science known as electrostatics is a complicated one. This isn't because it is extremely difficult for us to understand, but it can very complicated for us to explain. Of course it is possible to gain a good understanding of electrostatics through a proper study of the scientific principles behind it.

    We encounter electrostatics on a day-to-day basis. For example, electrostatics is at work when you remove plastic wrap from a piece of food, and the plastic sticks to ...

  • Crammers Guide To Survival In Hsc Exams
    By: George Li | - Crammers guide to survival

    First we should say: do NOT cram if you have a choice. We do not recommend cramming as a sole solution to the HSC, as cramming definitely underperforms consistent study in the long run. However in life, unforeseen events happen and you may find yourself in a situation where you have only a few days, or even just 1 day, before a major exam.

    Often if something happens and it is of no fault of your own, the school may be lenient and make arrangeme ...

  • Understanding Quantum Physics And Sub-atomic Particles
    By: Joseph Rettig | - Quantum Mechanics, generally called Quantum Physics, is the relationship shared between energy and matter. The word "quantum" is Latin for "how much". The mechanics of this refers to a unit that quantum theory assigns as a measurement to certain physical quantities in very small amounts. In essence, quantum expressions are usually looked at and studied on a sub-atomic level with sub-atomic particles. Sub-atomic particles are small. If an atom was as big as a house, the sub-atomic particle would ...

Joe was involved with gangs from the age of 13 to 18 and that alone should have sealed his fate to nothing more than a prison sentence or slow ride in a hearse -at best. So the question then arises how does such a lost human being go from one side of the pendulum of chaos and self-destruction to the complete opposing side of inner peace and sel ...

Without going too deep, the implication is that the experimenters are somehow connected to the experiment itself and no matter what they do, they are unable to prevent their influence over it. On the level of meta-physics this is evidence of our oneness with everything. Somehow we are connected to everything outside of us and have access ...
