GEOMETRY OF FAST FOOD – Part 1: Hunting For Deals
Fast food joints always offer a confusing long list of deals! There are just too many sizes, combinations and prices to choose from. But here too our old friend Geometry (by now we are friends with it right? helps us out! It can not only find the best fast food deals, but can also make it taste great!
Fermat and Home Wiring: How optics helped hook up a fridge
In an earlier article we saw how light always finds the quickest path. And that trick even helped us save the life of a drowning swimmer! Today we will see how this fact – called Fermat’s Principle – helped in doing some wiring at home. A simple shifting of a refrigerator at home posed a shortest path problem and we had to turn to Monsieur Fermat to find it.
Easter, Eggs and Equations – a fun quest!
Easter conjures up images of colorful, artistic eggs and hunting for them is so much fun! So much so, the surprising goodies tucked away in games and software have come to be called Easter Eggs. But then what do they have to do with EQUATIONS?
Comet C/2011 L4 (PANSTARRS): A live naked Eye COMET in evening SKY
Comet C/2011 L4 (PANSTARRS), is a non-periodic comet discovered in June 2011, that is expected to be visible to the naked eye when it is near perihelion in March 2013. The comet was discovered using the Pan-STARRS telescope located near the summit of Haleakala, on the island of Maui in Hawaii.
Algebra v/s Geometry: a battle that claims a thousand words!
What?? Algebra versus geometry? Aren’t they on the same side? i.e. against us?
No, not in our classrooms. And we’ve already sided with the wrong combatant.
Here, ‘algebra’ is the abstract, symbolic way of explaining concepts as against ‘geometry’ which presents them in a graphical, pictorial form. Our teaching almost exclusively employs the first approach. As an example, try answering any one of the following question.
The Night Sky – The space above our Head
The people who observe the sky on regular basis are Amateur astronomers. Amateur astronomers today are exceptionally fortunate to be living in an era when high quality, and very large, optics are so little expensive. In the first half of the 20th century the telescope deluxe for the amateur was the 6-inch refractor.
Observation with Naked Eye Object – Astronomy – Part 2
Naked Eye Comets
A comet is an icy small Solar System body (SSSB) that, when close enough to the Sun, displays a visible coma (a thin, fuzzy, temporary atmosphere) and sometimes also a tail. These phenomena are both due to the effects of solar radiation and the solar wind upon the nucleus of the comet.
Observation with Naked Eye Object – Astronomy
The only way to see the objects depicted in those wonderful photographs in text books and on websites is to own a telescope and a CCD or other type of camera. To see small details in the moon, and to view cloud patterns of Jupiter, a telescope is required.
Our Solar System – An Introduction
The stars which circle around our Sun consist of our solar system. In all there are planets which circles around our Sun. The Sun sits in the middle while the planets travel in circular paths (called orbits) around it. These nine planets travel in the same direction (counter- clockwise looking down from the Sun’s North Pole).
I am an Astronomy lover, are you?
I wanted to make our child and we understand how important Astronomy is which a small amount of knowledge I have. I have been popularizing astronomy since past 10 year from now. In 1995 which Comet Hale Bopp arrived and few eclipse held in India, I visited almost 100+ schools, colleges and institutions to deliver talkson various topics of Astronomy.
