On the morning of June 30, 1908, a massive explosion occurred in the skies over Siberia. The explosion flattened an estimated 80 million trees over an area of 2,150 square kilometers (830 square miles), and eyewitness reports suggest that at least three people may have died in the event. The explosion is generally attributed to… Continue reading The Tunguska Event: A Natural Disaster of Epic Proportions
The speed of light is a fundamental constant in physics, and it is assumed to be constant in all frames of reference. This means that no matter how fast you are moving, you will always measure the speed of light to be the same. However, there is some experimental evidence that suggests that the speed… Continue reading The Speed of Light: Constant or Variable?
In a world dominated by large smartphones, the demand for small phones has decreased significantly. In this article, you will learn which factors are responsible for the lack of interest in compact devices. Smartphone screens have been getting bigger and bigger for years, and it seems that the trend will only continue. But what about people who… Continue reading Why Don’t People buy Small Phones?
Our solar system is a symphony of planetary noises, from the howling winds of Venus to the crashing waves of Jupiter’s Great Red Spot. While we can’t hear these sounds directly, we can use instruments to record them and then play them back for us to hear. The most familiar sounds from other planets come… Continue reading The Sounds of Other Planets: A Symphony of Planetary Noises
Can minerals be absorbed through the skin? When summer arrives and temperatures rise, many of us are drawn to the sea. Then it is time to swim, drift and enjoy the feeling of salt water on our skin. When it comes to saltiness, not all seas are equal. While the salt content is rather low… Continue reading Can the body absorb salt through the skin?
Yes, the sense of taste is inherited. Studies have shown that there are genes that affect our ability to taste different flavors, such as sweet, sour, salty, bitter, and umami. For example, one gene called TAS2R38 is responsible for our ability to taste the bitter compound phenylthiocarbamide (PTC). People who have a certain variation of… Continue reading Is the Sense of Taste Inherited?
The Big Bang is the prevailing cosmological model for the universe. It states that the universe was once in an extremely hot and dense state that expanded rapidly. This expansion caused the universe to cool and resulted in its present size and composition. The Big Bang theory is based on Albert Einstein’s theory of general… Continue reading What is the Big Bang? A Short Answer.
Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science is different from other types of knowledge because it is based on evidence and can be tested and replicated. Scientific knowledge is always provisional, meaning that it is subject to change as new… Continue reading What is science simple definition
Physics has always been about figuring out the structure of the world, and the same can be said about our brains. However, physics often comes to conclusions that conflict with concepts fundamental to our minds, such as the realness of space and time. So, the question arises: are time and space objective realities or human-invented… Continue reading Is Space and Time Real? A Neuroscientific Exploration
Plastic waste is one of the biggest problems facing our planet today. Despite efforts to recycle, only a small percentage of the plastics produced by humanity have been successfully reused. The rest is either leaching toxins in landfills or disrupting ecosystems. But what if nature held the key to solving our plastic problem? Insects, bacteria,… Continue reading The Future of Plastic: Bioengineering and Enzymatic Degradation
