Number of words: 531 Relativity theory has made the structure of electrodynamics much more elegant by unifying the concepts of both charges and currents and electric and magnetic fields. Since all motion is relative, every charge can also appear as a current-in a frame of reference where it moves with respect to the observer -and … Read more

Number of words: 531 The creation and destruction of material particles is one of the most impressive consequences of the equivalence of mass and energy. In the collision processes of high-energy physics, mass is no longer conserved. The colliding particles can be destroyed and their masses may be transformed partly into the masses, and partly … Read more

Number of words: 455 When we study the universe as a whole, with its millions of galaxies, we have reached the largest scale of space and time; and again, at that cosmic level, we discover that the universe is not static-it is expanding! This has been one of the most important discoveries in modern astronomy. … Read more

Number of words: 261 To experience the unification of seemingly separate entities in a higher dimension we do not need relativity theory. It can also be experienced by going from one to two dimensions, or from two to three. In the example of a circular motion and its projection given opposite the opposite poles of … Read more

Number of words: 120 Anybody who wants to repeat an experiment in modern subatomic physics has to undergo many years of training. Only then will he or she be able to ask nature a specific question through the experiment and to understand the answer. Similarly, a deep mystical experience requires, generally, many years of training … Read more

Number of words: 588 Cement and concrete haven’t changed much as technology in over a hundred years, but researchers in Colorado are revolutionizing building materials by literally bringing them to life. The method developed, presented January 15 in the journal Matter, combines sand and bacteria to build a living material that has structural load-bearing and … Read more

Number of words: 1,362 In the developer series, we reach out to developers, practitioners and experts from the machine learning community to gain insights on their journey in data science, and the tools and skills essential for their day-to-day operation. For this week’s column, Analytics India Magazine got in touch with Konstantin Yakovlev, a Kaggle … Read more

Number of words: 923 New Scientist reports that doctors have used therapeutic suspended animation for the first time as part of a carefully designed human trial. The procedure, called Emergency Preservation and Resuscitation (EPR), is a way to try to save the lives of people with severe traumatic injuries like gunshot damage—patients who have lost the majority of … Read more

Number of words: 364 In a boost to the fight against the menace of counterfeiting, two researchers at the Hyderabad campus of the Birla Institute of Technology and Science have developed an ink that changes colour when exposed to acid vapours and reverts to its original colour when exposed to base vapours. The ink contains … Read more

Number of words: 943 Perhaps the biggest hurdle to humankind’s expansion throughout the solar system is the prohibitive cost of escaping Earth’s gravitational pull. So say Zephyr Penoyre from the University of Cambridge in the UK and Emily Sandford at Columbia University in New York. The problem is that rocket engines work by jettisoning mass … Read more
