Understanding scope of Science with the help of Cricket


Most of us understand things in life when we look around for examples. Some things are easier to be understood when correlated with everyday things. One such correlation as an example to understand the scope of Science can be found in Cricket.

The game of Cricket!

Cricket is a game of ball, bat and wickets. It is a game in which a bowler bowls a ball to a batsman playing at other end of pitch trying to defend or attack the ball while saving his wicket. And there are other players who are fielding in the ground. And so many other aspects to it regarding the rules and regulations as well as the nomenclature.

Scope of Cricket

However cricket is played at various levels such as gully cricket, box cricket, in a ground and in a stadium. As well as various formats like T20, ODI and Test. In each format the number of overs are different and the strategy of game differs. As well as where it is played, the context of the game changes. However fundamental of the game remains the same. A batsman playing against a ball bowled by the bowler and trying to score runs.

In gully cricket it may be considered out if one hits the ball hard enough or in the sky beyond limits considering it may hit someone or break someone’s window glass. Whereas the same stroke with power would fetch one a boundary or a sixer in a stadium. In the context of the game and the situation the norms and expectations are changed.

Basic Science

Now let’s take the same stuff into Science. When one tries to understand the concepts of science like Light, Atoms, Energy, Plants, Human body systems and so on, at the school level, they are expected to gain basic understanding of the concepts. That may include, not limited to, the definitions, descriptions, examples and understanding the whats. Sometimes it includes the why and how of a concept in a simpler way without going into details, just like the gully cricket.

The same concept can be stretched on to understand in detail at college level, research level and some questions remain unanswered by science till date. We may reach to the closer approximation or explanation of something but we cannot affirm the confirmation of many things. Science certainly can explain and reproduce many events completely but some remain to be puzzled yet.

When any particular concept or topic is taken up in detail, it starts to behave similar to an international match in an championship event. It has many facets to it and everything is almost dynamic. So what should be the approach to learn Science. What is the simplest explanation of Science like that of cricket.

Approach to Science!

To be good at Science and to embrace it completely one must continue to be curious, be inquisitive to understand something well, ask questions, observe things acutely and connect all the information they have absorbed and if possible conduct experiments or further observation to base their understanding on firm provable and reproduceable facts and experiments.

Growth in Science

Often there may be no direct answers to the simple questions one may have at early age in school to the questions like why there are thunderstorms, how does it rain exactly, how do plants grow, why there are only 7 colors in a rainbow and many other things. Even though we may explain things in a simpler way by introducing the concepts like photosynthesis, refraction, precipitation and many other at early stage. Mere definitions and name should not be considered to be the final conclusion of something. By asking further questions one may learn more and giving rise to even more questions. In the quench to understand something a new discovery may await us. That’s how Science grows.

An example makes is easier to understand.

But all be said, within the scope of the game you must restrict yourself from playing shots in the air in gully cricket and hit harder in stadium. Same way one must learn to be flexible yet firm to understand and immerse in Science.

Dmitri Mendeleev

Dmitri Ivanovich Mendeleev

8 February 1834 – 2 February 1907


Dmitri Ivanovich Mendeleev was a Russian chemist and inventor. He is best remembered for formulating the Periodic Law and creating a farsighted version of the periodic table of elements. He used the Periodic Law not only to correct the then-accepted properties of some known elements, such as the valence and atomic weight of uranium, but also to predict the properties of eight elements that were yet to be discovered. Mendeleev was born in the village of Verkhnie Aremzyani, near Tobolsk in Siberia. In 1907, Mendeleev died at the age of 72 in Saint Petersburg from influenza.


Dmitri Mendeleev is often referred to as the Father of the Periodic Table. He called his table or matrix, “the Periodic System”

I saw in a dream a table where all elements fell into place as required. Awakening, I immediately wrote it down on a piece of paper, only in one place did a correction later seem necessary.

Mendeleev, as quoted by Inostrantzev

To get the best experience of full moon, observe the position of Moon and Sun, from your location today onwards. Once you get the hang of the position when the Sunrises and Sunsets, while at the same time knowing the position of Moon in the sky from your location helps in getting the first glimpses of Moon as it comes out of the horizon. If you are lucky, you will see orange-red shining Moon, that looks just like the Sun.

On 7th May 2020 Moonrise happens right after the Sunset. This is because Moon is exactly opposite to the Sun in it’s orbit around the Earth. This happens on every Full Moon. Hence it is the best time to enjoy Skygazing as you will be able to see, Sunset, Moonrise, Stars and Planets in the span of 1 to 2 hours, covering your quest for a total experience.


As you look at the Sun from 6:30 PM in the west, sky will change it’s colour from blue to orange to red to dark blue and then eventually turning black. As the Sun goes down the horizon or in our case of being in urban city like Surat, it will be behind some buildings. Only near the Tapi river or in the outskirts of city, do we have the luxury of being able to see the horizon.

Sunset between building in Surat.

Patience is the key.

Wait and watch for the Moon. It’s time to face east now. If you have observed the Moon on 5th and 6th May, you will get clarity on where it rises from in your location. If there are buildings obstructing in your vicinity, it’s better to position yourself on top of a building or move somewhere so that you can see the horizon.

Moon isn’t visible right away. Even though Moon comes above the horizon, it is not visible to us due to pollution in city as well as the luminance is not at it’s maximum. Once it goes up around 10° above the horizon, it can be easily spotted. If you are lucky to be in the right place and have keen observation, you may be able to see it below that point as well.

Moonrise in Surat

Moon is magic. Once you see the first glimpse of Moon rising behind the trees or dark clouds or some far off houses, you will be captivated in the magic. It takes around 15-20 mins for the Moon to be clearly visible. So in this case it will be around 7:30 PM you can be sure to get a clear glimpse. To be able to see before that luck is needed.

Feel spiritual vibes while skygazing on Buddha Purnima.

Moon changes it’s colour as it comes up in the sky. When you first see the Moonrise, it may shine bright red, dark red or pinkish in colour. As it goes up it certainly changes from being red to being yellow and then as it goes up in the sky it changes to its popular full moon white bright colour. If you cannot see the Moonrise, you just have to wait until it has gone around a building or rise past some obstruction for it to be visible from your balcony, window, terrace or house.

Look for planets and stars as well. As you wait while Moon is rising or once it has been seen until your heart is filled with joy, happiness and serenity, you can look for VENUS which will be visible in the West. Also you can look a bit towards the South-East near the horizon or a bit high up by 9pm, to be able to see ANTARES.

Feeling hungry is common. You may get tired by constant gazing of sky from 6:30 PM till 8:30 PM, so it is better to keep some light snacks with you as well as sufficient water. It is best accompanied with some light music. By the time you are done with looking at all the shining objects in the sky, you will be hungry for your dinner, so go and grab something to eat.

Wonderful experience. Looking at the sky on any given day or night is a beautiful experience but when you have a lot happening on a single night within a span of hours then it’s the best experience. Enjoy sky gazing with your friends or young children.

Looking at Moonrise on a Full Moon is captivating experience that you can never forget.


On 7 May 2020, the distance of Moon from Earth is around 3.59 lakh km, while on 15 May 2020 it goes far off 4.0 lakh km. Moon comes close to Earth that’s why it appears bigger than usual and the Full Moon is sometimes referred to as super-moon.

Let us know how your experience was in the comments section below. Feel free to ask any questions related to Full moon or sky-gazing in general. Share your view and share it with your friends.

SKYGAZING : Location of Planets in Summer Sky as seen from Surat, India

In Surat, India
Co-ordinates are 21.1 ° N latitude 72.8° E longitude

May 2020

Planets –
Mercury, Venus, Mars, Jupiter, Saturn

Sense of Direction, Observation Skills & Patience a lot of it.


Mercury is an interior planet with respect to the Earth. It is the closest planet to the Sun. So you will see it either right before Sunrise or after Sunset. It is very small planet so spotting Mercury in the sky is quite some challenge. It might take some time to get a hang around it as well as your local conditions must be good enough to be able to see it as it will often be seen only around the horizon where maximum obstacles are seen or pollution interferes.

A planet is said to be inferior or interior with respect to another planet if its orbit lies inside the other planet’s orbit around the Sun.

In Surat which is an urban city with dense population and vehicular movement, sky at the horizon is usually obstruct by buildings or covered in dark clouds caused by pollution. You may either take a vantage point at a building’s terrace or find an open field near Tapi river where you can see horizon.

In the month of May, Mercury is close to Sun in the sky, so it is not possible to see it. So you may enjoy looking at Venus during this time. Mercury revolves the Sun in 88 days, so it goes around in the sky from East to West with in that duration.

Position of Mercury as seen from Earth in May 2020


Venus is the brightest object in the night sky after Moon. It shines bright enough to be seen in the presence of Sun at Sunset or Sunrise. You may get it confused with Sirius star which looks almost similar but you just need to find if it’s twinkling or not to be able to identify Venus. Yes, planets don’t twinkling in sky due to their proximity to Solar system as well as they don’t have their own light. Planets reflect the light of Sun, just like the Moon.

Venus is interior planet like Mercury. It is seen either before Sunrise or after Sunset as per it’s position in the orbit around Sun. In May it is seen the west after Sunset.

And yes, planets undergo phases just like the Moon, however it is not possible to see the phasing details with naked eye. However using a sufficiently strong telescope, phases of Venus can be seen just like how Galileo did.

Venus is shining bright in the west sky right after the Sunset. It shines bright enough to be confused with a light bulb. Follow the Sun in the evening and enjoy the Sunset. Right after sunset, you will see a bright star shining in the sky in the same direction, that is Venus. Venus is visible until 9 PM or so in Surat. The altitude of Venus will be around 30 degree from horizon when you will be able to see it the best.

Sunset is at 7:05 PM today.


Mars can be seen from 2 am onwards in Surat towards the South-East sky. All planets follow the elliptical. Once you get a hang of it, you would know where the planets may be located. Currently all the 3 exterior planets visible to naked eye are in sequence in the night sky.

Mars, Jupiter and Saturn are superior planets visible to naked eye. Since they have orbits larger than Earth, they follow the movement of sky as seen from Earth. You can see these planets rising and setting down. Currently the rising hours are near midnight so they can be seen for around 3-5 hours depending upon the Sunrise.

A planet is said to be superior with respect to another planet if its orbit lies outside the other planet’s orbit around the Sun.



Jupiter is visible first in the east sky at night in the sequence of the three exterior planets visible with naked eye. It can be seen clearly from 12:30 am onwards.

Jupiter is very bright and easily spotted in the sky. Once identified, it can be taken as a reference to spot Saturn, which is very dim and Mars which is fairly bright in itself.


Saturn is following Jupiter in the sky as seen from Surat. As Jupiter rises high in sky sometime after that, Saturn will start to shine very dim. As it rises up in the sky and night starts to fall in, it gains some sharpness.

Sky gazing in Surat – May 2020

In Surat, India
Co-ordinates are 21.1 ° N latitude 72.8° E longitude

03-05-2020 8 PM onwards

Scorpius & Libra Constellation
Stars – Antares, Shaula, Rigil, Hadar, Spica, Regulus, Algieba


Sky at night keeps moving every hour due to the rotation of Earth. So the stars move across the sky over the night. Stars also appear 4 minutes earlier every night. So with change in month, as you keep observing every night, you will find stars have shifted their position compared to previous night. And if you look for long enough like 6 months, you will find the entire sky has changed over that duration, since the Earth has rotated across the other point in it’s orbit around the Sun.

Stars appear 4 minutes earlier every night.


It is mid of summer here in Surat as we move into the month of May,. Surat was under lockdown from 25 March 2020 due to the on-going corona virus caused COVID-19 global pandemic. So there was not much activity carried out in terms of sky-gazing during the month of April 2020. However we start with new enthusiasm in May 2020.

Dark sky is clear. The best location to start look at is in the East for it is where the sky rises and it helps to keep track of the timing, position and movement. Little after sunset, if you look towards the South-East sky you will be able to spot a bright star – ANTARES. This will be a good starting point to explore the south sky.

Let your eyes get adjusted to the darkness. It will take around 30 minutes for a good enough experience.

Once you identify Antares, which is the brightest star in Scorpius constellation as well as one of the brightest star in the night sky. It will appear slightly reddish if you observe carefully. Following the Antares, you can go up and track the 3 stars of the constellation which look like the claws of the scorpion image. Two of them will be distinctly visible, the other one will take some time for you to adjust and identify.

Then it’s time to track SHAULA, which is bright enough to be spotted easily. Once you have the overlying area of the constellation. Keep looking for other smaller stars. It will depend on light pollution in your surrounding, air pollution, your eye sight, clouds in sky and other parameters. But if you keep looking, you will develop an habit of finding out details of the constellation and be able to find other dim stars. Hence completing your observation and tracking of Scorpius constellation.

Use star tracker apps like Sky-View or SkySafari to identify and spot the stars easily with the help of view finder.

It may take around an hour to be able to completely get the imprinting of a scorpion image on whose comparison in ancient world drew the pictures in their minds about the sky. At around 10 PM, the constellation would be high enough to be completely in view. If you are surrounded by buildings, then wait for the constellation to rise higher. You will be able to see it in the zenith, highest point in sky at around 12 AM or so. That would be the best time to view. If you are a night owl, then it is the best experience.



As you go higher in sky above Scorpius, you will be able to see 4 stars forming a quadrilateral. These stars are part of Libra constellation. 3 of those stars will be visible easily. Use app to see dimmer stars. Surrounding the sky in that area, other 4 to 5 stars are fairly visible and shine brighter, captivating your attention.

Facing exactly towards the south, you will see two stars shining bright like a light bulb in some buildings. Those two stars RIGIL and HADAR will stay close to the horizon. Other stars facing south which shine bright during the entire winter season in Surat are CANOPUS & REGOR.

Sky appears different based on your latitude. You will never be able to see some stars from your location. You will have to go either North or South.

If you look up the night sky over your head after 10 PM, you will see a bright star twinkling, that is SPICA. It is part of VIRGO constellation. Other stars are not so visible, especially due to the close proximity to bright Moon.

Moon was shining bright in LEO constellation for the last 2 nights. The bright star shining towards the west of moon was REGULUS. You can also see ALGIEBA. Leo will be going down in the west sky as night falls.

No access to North facing sky tonight. Some updates coming soon.

Some stars don’t seem to be twinkling, they are planets.
