Time is the fourth dimension, other than the three dimensions of space. Time makes change possible or else we would be living in a static universe.
Neodymium magnets are permanent magnets consisting of rare-earth elements. They have useful applications in many fields, but can cause fatal injury if not handled properly.
For many centuries, scientists from various parts of the world have conducted several experiments before they could state the relationship between magnetism and electricity. The article below explains the various concepts related to both these entities.
Magnets, besides being fun to play with, have many uses. They are used in consumer as well as industrial goods. Let’s get to know more about the uses of magnets.
The use of nuclear power is debatable, with some proposing it for the amount of energy produced, while some dead against it because of its potential threat to environment and human life. The advantages and disadvantages of nuclear energy provided by ScienceStruck will help you form an opinion about the same.
A lever is a type of simple machine that is used to lift weights. Several modern machines are based on the application of this device. Read this ScienceStruck post to gain more information about levers and their various examples.
Pulleys are categorized as a type of simple machine consisting of a grooved wheel and a rope or cable. These devices help us to lift heavy loads in an effective manner, as well suspend various objects in the air (for example: a flag). Read this ScienceStruck article to know more about the various types of pulley systems and their working mechanisms.
Archimedes was a prodigy in the field of mathematics and science, where he pushed the boundaries of both subjects to obtain a profound result through careful research, calculation, and observation. He is known as the ‘father of mathematical physics’, and the ‘father of integral calculus’, quite rightly. Let’s take a look at how the inventions of Archimedes have paved a way for modernized versions of his works.
When sound waves travel through a medium, the particles of the medium vibrate. Vibrations reach the ear and then the brain which senses them and we recognize sound. Read on for an explanation of how sound travels.
Boyle’s Law provides an important formula to calculate the effect of changing pressure on the volume of a gas, and vice versa. It was put forward by a physicist Robert Boyle in the 17th century, and has proved very beneficial for scientists involved in the study of properties of gases.
One of the most important scientific breakthroughs of all times is Sir Isaac Newton’s universal law of gravitation, all thanks to the falling apple. Gravity is an invisible force that pulls/attracts all matter towards itself. The fundamental forces of the universe include the electromagnetic, strong nuclear, weak nuclear, and gravitational forces.
Next time when a physics professor says that the probability of your position at any given time, in the whole universe, is never zero, don’t think he has lost his marbles. This is where we can start with an explanation of the basics of quantum mechanics for dummies.
Isaac Newton was one of the most important figures in the field of science. We owe our understanding of the universe to his scientific discoveries. This ScienceStruck article tells you about the accomplishments of Isaac Newton.
One of the most interesting scientific phenomena, radioactivity has always attracted people for undertaking research on it and also for unraveling the scientific truths regarding its aspects. This ScienceStruck article explains in detail how radioactive decay works.
We all know that magnets attract iron particles. We have seen fridge magnets, other decorative articles, and even some toys that use magnets. We have heard of the applications of magnetism in daily life. But have we thought of who must have discovered magnets and when?
Optical illusions are caused by the interestingly complex structure of our eyes and the brain. To know about the causes of optical illusions, read on...
What are optical illusions? With the help of colors, specific patterns, and light, images are created in a way such that the brain perceives them as different from what they really are. Read this ScienceStruck article to find how optical illusions work.
It is not exactly right to say that electricity was invented. We could say it was discovered and ways were devised to use it. Who discovered electricity and when was it discovered? Puzzled? Read on to find out.
Magnetism isn’t just that fancy little pulling force which attracts iron objects, it’s probably the biggest force keeping us alive. Technically speaking, a magnet is any object that creates a magnetic field. This magnetic field essentially pulls ferromagnetic objects like iron, nickel, and cobalt towards it. Although invisible, the magnetic field is the most defining feature of magnets.
This article includes information regarding the uses and applications of vacuum tubes. They find uses in a variety of electronic devices.
Albert Einstein is well-known for his brilliant contributions in the field of physics and in particular, famous for his theory of relativity. The accomplishments of Albert Einstein are many and varied. They range from discoveries of the mysteries of the universe to being a promoter of peace and freedom of expression during a time when fear of communism was rampant.
The enigmatic quantity called energy can be roughly defined as the ability of any physical entity to do work against exerted forces in the surroundings. Learn about various manifestations of energy, along with working mechanisms and related examples.
Certain solids emit electrons from their surfaces when subjected to heat (thermionic emission), electromagnetic radiation (photoemission) and/or an electric field (field emission). Much of electronics, including vacuum tubes, cathode-ray tubes in their various manifestations, and electron microscopes, depend on the emission of electrons from metals and the manipulation of these electrons to perform various tasks. Here’s more on the history and theory of electron emission from solids.
Here is a brief, selective, life sketch of Albert Einstein, the most celebrated scientist ever. He has contributed immensely to the mankind with his work. Discover his life in this article.
