BLOG #9 - THE NATURAL HISTORY OF BIRDSONG

Birdsong is an exceedingly complex and sophisticated communication system. It is produced from the bird's syrinx, a soundbox at the junction of the two bronchi, which lead to the lungs. Air from the lungs is passed over membrane in the syrinx, which then vibrate, producing sound waves.

The Anatomy of a Bird
               Because there are 2 bronchi with membranes, sound can emanate from each and combine higher in the vocal tract, producing a large variety of sounds. Complexity in the vocal muscles translates into more complex songs. Birds sing to defend their territory and to attract mates. Some species even sing when persuaded by the predators to convey how robust they are.
               On the whole, males sing more than females. The male brown thrasher has command of some 2000 - different songs. Male and female birds sometimes sing duets, and group of birds may sing together to defend a territory. Some species are especially adept at mimicry. Some scottish starlings reproduce the sounds of sheep; some english starlings even mimic the city buses.

BLOG #1 - THE BIG BANG - COSMIC BEGINNINGS

Accepted astrophysical theories posit that at one point there was nothing: no stars, planets or galaxies - not even the space itself. The matter that makes up everything that now exists was concentrated in a single, extremely dense point known as a singularity. The force of gravity in a singularity is so great that the fabric of space time curves in on itself. In an instant known as the big bang, however, the contents of the primordial singularity escaped - and formed the universe.                The big bang is a catchy shorthand for a complex astrophysical theory, backed up with sophisticated calculations. The term was coined in the 1950s by British astronomer Fred Boyle, a proponent of a theory of the universe as a steady state. In fact, Boyle used the term derisively. Though the name stuck, it gives a false impression, making it seem as though the event that unleashed all the energy of the universe almost 14 billion years ago was an e...

Questions that question YOU from YOU - PART 1

Sometimes we get too caught up in our every day lives that we tend to forget one of our most basic instincts as humans — to question. And our lives have indeed become so easy and so simple, that we never get curious anymore. Thanks to the tech, obviously. After all, we are i the 21st century. So, in this piece for you, I've got some questions to make you spark the plugs into your grey matter.(not the GRAY matter,  its the grey matter) Now what's the grey matter first ? Grey  matter  contains most of the brain's neuronal cell bodies. The grey  matter  includes regions of the brain involved in muscle control, and sensory perception such as seeing and hearing, memory, emotions, speech, decision making, and self-control. Enough for the intro, I guess. So, here are the questions. Q. Why do we all FEAR death ? Q. What is REALITY ? Q. Is our SOCIETY teaching us the WRONG things ? Q. Is TIME only a concept made by humans ? Is it something we RESTRICT ourselves with ? Q....

Some Special(yet some common) Things to START BELIEVING in yourself AGAIN - PART 2

  ....  to be continued. Thank you for your love for the part 1 of the blog, here's the second part of the series. 4) FIND and OPEN your HEART While step 3 is about acknowledging and accepting the pain, step 4 is about reconciling with a cold and unopened heart. Ask yourself this one question: do you fully love yourself ? NO !!  No need to be shocked. It's very common for all of us in this hectic world. So, accepting your flaws and your fault is one thing, but loving a person who can have your thoughts, your emotions and most importantly your mistakes? That's a completely higher level of self-love. That's something most of us miss today. What to do now ? Question yourself. Discover your life story. Trace your path way back from your childhood to the person you are now.  Understand yourself in the most intimate way ever possible, and find a reason for that damn every negative emotion, every shameful act, every word or mistake you regret even today. In this journey of ...
