How Technology and Bioengineering have changed the face of healthcare

Gone are the days when doctors had to cut and prod in order to find the ultimate cause of someone's medical problem. Now with all the advances in technology, especially in the area of nuclear imaging, a simple scan can most often get to the root of the problem without the need for what was once a common practice, exploratory surgery. In fact, it wasn’t all that long ago in human history when x-rays were state-of-the-art technology and that is…

What you need to write better chemistry notes (and what not)?

Chemistry is one strange subject. It begins with a simple substance and goes above complex polymers - and, down to subatomic particles. I have been writing a lot recently on how to read, revise and make notes etc., to help you become a better student. Class notes aren't always the best solution and if you are aspiring to become a chemistry scholar one day - you must rise above the classroom notes and write your own for the change. This…

Interesting Facts about Blood and Blood Cells

Like all humans have red colored blood, there are few organisms which have varying blood colors. Spiders and octopus have blue color blood, cockroaches have white/colorless blood, grasshopper, leeches, and some varieties of earthworm have green color blood and so on. Apart from these, there are more facts about the blood. In this article, few interesting facts about Blood and Blood Cells of the human body. Blood is the only fluid connective tissue in the human body and it plays…

Meet A1689B11 : The oldest spiral galaxy ever discovered

In a collaborative attempt, astrophysicists from different institutions have found success in discovery of A1689B11 - a spiral galaxy that's said to be the oldest discovered. The research reports an integral-field spectroscopic (IFS) observation of this gravitationally lensed spiral galaxy. It is the most ancient one till date and is calculated to be 11 billion years old, which means it existed after just 2.6 billion years after the big bang happened. Big bang happened around 13.7 billion years ago, which means this galaxy…

Perseids : Long Story Short

What are perseids? Perseids are the regular and most predictable meteor shower which appear regularly every year. They are associated with Swift Tuttle comet and appear to rise from the radiant in the constellation Perseus. Swift Tuttle comet, formerly known as 109P, travels toward Earth's part of solar system every 133 years leaving traces of perseids. It was last seen in 1992 after its discovery year 1862 AD. Next time Swift Tuttle is predicted to be seen in 2126 AD. Perseids,…

Examination Strategies : Tactics & Tips

Every student or graduate knows how hard the first experience of passing exams is. Preliminary preparation starves the nervous system and the physical condition of the human body, however, the exam itself is always a stressful situation, which requires a candidate a great manifestation of mental and physical abilities. Therefore, just the knowledge of a subject is not enough for the exam. The examinee needs to have high self-organization, ability to keep his emotions and absolute confidence in his abilities.…

Nobel Prize Winners Chemistry 2013

The Nobel Prize in Chemistry 2013

  Classical mechanics is considered to be just opposite to quantum physics in terms of theory and practical models. Classical mechanics, especially Newtonian Mechanics, and quantum mechanics are definitely two fundamental but equally different branches of physics having no significant connection to each other. These completely disjoint subjects were glued by the work of the trio of Martin Karplus, Michale Levitt and Arieh Warshel, the professors of chemistry from the universities of United States of America in decade of 1970s.…

Finally a Physics Nobel Prize for Higgs boson Theorists

The 2013 Nobel Prize for physics has been awarded to Peter Higgs and Francois Englert for their remarkable contributions to the theory of Higgs boson "God Particles". It came after 50 years Peter Higgs, Robert Brout, Gerald Guralnik, C R Hagen, T. W. B. Kibble and Francois Englert independently announced the existence of Higgs boson in 1964 to put the theory to the world how the mass comes into existence in objects. On 8th October 2013, the Royal Swedish Academy…

Real Sequences

Sequence of real numbers A sequence of real numbers (or a real sequence) is defined as a function $ f: \mathbb{N} \to \mathbb{R}$ , where $ \mathbb{N}$ is the set of natural numbers and $ \mathbb{R}$ is the set of real numbers. Thus, $ f(n)=r_n, \ n \in \mathbb{N}, \ r_n \in \mathbb{R}$ is a function which produces a sequence of real numbers $ r_n$ . It's customary to write a sequence as form of functions in brackets, e.g.; $…
