It’s unavoidable that soda bottles or cans are moved around in shopping bags, or fall down on their side and roll on the floor or ground. Or it may be because some pranksters think it’s funny to see a soda bottle or can explode in your face. During these times, it’s safer not to immediately open the soda or else you’d get wet from the exploding foam. But why does […]
Posted by WhyDoes on Sep - 5 - 2009 - Comments Off on Why Does Someone have High Blood Pressure?
Blood is constantly moving inside the human body. It is distributed to all parts of the body so it can deliver oxygen to internal organs. This ability to move is due to the pressure exerted by the heart when pumping. The faster the heart pumps, the higher the blood pressure rises. Blood pressure is at its highest when the heart pumps the blood, which is what we call as heartbeat. […]

Sugar, like salt, dissolves easily when mixed with water. The sugar molecules break up easily and do not reform again after the water molecules pull them away from each other like magnets do to iron fillings. The attraction between the water and sugar molecules depends on the charge each one emits. The sugar molecules are known to have hydroxyl groups that have a slight negative charge. On one hand, the […]
Posted by WhyDoes on Sep - 5 - 2009 - Comments Off on Why Does the Pythagorean Theorem work?
All of us had, in one time or another, encountered the Pythagorean Theorem. A fundamental formula in Geometry, the theorem was first found stated in Babylonian text around 1900 BC. It was around 500 BC, however, that a proof to the theorem was discovered. Traditionally, Phythagoras, a famous Greek mathematician, was believed to have found the proof. This claim, albeit credible, wasn’t thoroughly discussed in detail until the publication of […]
Posted by WhyDoes on Sep - 5 - 2009 - Comments Off on Why Does the Right Lung have 3 Lobes?
In our Biology class we learn that we have two lungs, the left and the right. Looking deeper, we observe that the left lung seems to only have two lobes, while the right lung has three. The right lung may be shorter, but it’s wider than the left. Why does our right lung have three lobes and is wider than the left lung? The answer is to make space for […]

Observers of American politics have already said this: the U.S. Government is strongly supportive of Israel. Despite Israel’s socio-political activities against Palestine and Lebanon, the United States continues to funnel economic and military aid to Israel’s coffers. Why does the U.S. support Israel? The reasons may be found in three contexts: historical, religious, and economic. In History The historical connections of Israel with the Western countries began after World War […]

Unlike climates that normally stays the same for much longer periods, weather changes so often each day or each hour. One day we have sunny skies, the next day we’ll have a cloudy day. Sometimes, it would be rainy one morning, and sunny and warm in the afternoon. The weather changes so often it is difficult to predict. But why and how does the weather change? Air Mass and Pressure […]
Posted by WhyDoes on Sep - 5 - 2009 - Comments Off on Why Does Fluid Build Up In The Lungs?
Our lungs are two large balloon-like organs inside our chest cavity, nestled behind our heart and the upper part of our stomach. Through the help of the lungs and the body’s circulatory system, oxygen is distributed to internal organs, and carbon dioxide is expelled from the body. This pair of spongy organs is normally filled with air, and not fluids. However, when fluids build up inside the lungs, it prevents […]
Posted by WhyDoes on Sep - 5 - 2009 - Comments Off on Why Does Smoking Increase Blood Pressure?
Let’s admit it: Smoking feels good. Each deep drag triggers pleasure receptors in the brain. Dopamine, the “happy” hormone, is released, and as a result, smokers feel “high” without the bad effects, which include drowsiness, depression, and even hallucinations. Those bad effects, however, are just superficial. What really hurts smokers the most are the hidden effects smoking has on the human body. One of these is an immediate increase in […]
Posted by WhyDoes on Sep - 5 - 2009 - Comments Off on Why Does the Leaning Tower of Pisa Lean?
The Tower of Pisa wasn’t leaning when it was built in 1173; it was as straight as a pole. It only began to shift direction shortly after construction due to a poorly built foundation and a loose layer of subsoil. It was leaning to the southeast, at first, before the unstable foundation shifted and started leaning towards the southwest. After a phase of structural strengthening in the early twenty-first century, […]
