Carl Sagan

My life is a little hectic at the moment due to UCAS (University Application) deadlines and so on. While in the middle of composing my personal statement, I found a small tribute text I had written about Carl Sagan last year as a response to the following question for an application.

If you could have dinner with anyone alive or dead, who would it be and why?

And I followed up with this:

I would love to have dinner with Carl Sagan.

On Public Opinions of Space Exploration

While my lovely co-writer friend Jiangmin has been having a summer holiday filled with medicine, biological research and UKCAT revision (good luck!), she’s headed off this week to complete a Summer school course – just wanted to say, all the best Jiangmin!

I thought this week I might leave Physics aside for a little and talk about the importance of space flight and exploration, especially the Mars issue.


Many leading scientists believe that in order for humans to progress and maintain our survival we must think about progressing in terms of space exploration, whether that be missions like Juno and Cassini to aid research on planetary science, missions like Voyager – the furthest space craft from Earth to explore the outskirts of the solar system or actually sending humans to Mars which seems to either be the general public’s cup of tea, or not.

My Scottish Space School Experience

SSSLOGO_SMBonjour fellow bloggers and blog viewers, I just came back from a fantastic residential week at Scottish Space School and I just thought it would be great to share this great experience with you all.

The Scottish Space School, as I mentioned several months before in a “thoughts” post, is a residential week aimed at students in their second last year of high school who are interested in pursuing a career in Engineering, Space Exploration or something along these lines, and is situated in the University of Strathclyde, Glasgow. This year I was one of the lucky 100 students to be selected from over 500 applicants based around Scotland to attend the week running from 11th to 16th June 2017.

The week-long programme included different engineering workshops, lectures from senior NASA guests, talks from people who worked in the Space industry, fun social events and many more.

Dark Matter #2: Gravitational Lensing

heic1506e.jpgA couple of months ago I talked about a piece of evidence supporting the existence of Dark Matter which is the fact that the stars in the outskirts of galaxies were seen to move at a similar pace as galaxies near the galactic core, defying the norm of the Keplerian Decline.

Recap: Dark Matter makes up roughly 25% of the Universe, so it is five times more prevalent than ordinary Baryonic Matter. Physicists gave it the name Dark Matter not because of it having some mysterious evil property or anything of that sort, but because it simply does not interact with Electromagnetic Radiation. I agree Physicists are a creative bunch.

Renewables…you say?

Most of the energy we use to power technology come from finite sources which are not sustainable. This energy which may be in the form of either fossil fuels, coal or even nuclear fuels and so on will eventually be used up. However renewable sources such as solar power will not run out…..until the sun runs out of hydrogen fuel but that’s another story.

Even my trusty fx- 85GT PLUS uses solar power.

We are able to harness the light energy radiated by the sun by the used of solar cells. A solar cell is an electronic device made of semiconductors which exhibit the photovoltaic effect to convert light energy into electrical energy. Semiconductors are materials which lie between conductors and insulators. A conductor is a material which is composed of atoms in which electrons are easily freed from the nuclei. Even though it is able to form a current, it remains electronically neutral as there are the same number of positive protons and negative free electrons. An insulator, on the other hand, is a material which is composed of atoms which hold more tightly onto their electrons so they have no free electrons like conductors. Current is a measure of the rate of flow of charge through a material, with the electrons being the charge carriers transporting energy across a circuit.  Continue reading

Thoughts #9 – Scottish Space School

As you can probably infer from the title of this thoughts post, I was recently notified that I had made a successful application to the Scottish Space School programme. To be accepted onto the programme has been a dream of mine for the past two years as a former student from my school described her intriguing experience.

The Scottish Space School programme is designed for students into Science and currently progressing through the second last year of high school.It is a week-long Space-themed residential at the University of Strathclyde and features a set of lectures given by leading researchers, laboratory activities and workshops supported by NASA astronauts and engineers. On top of that, at the end of the week, 10 students are selected to go visit NASA’s Johnson Space Centre in Houston, Texas.

I am incredibly excited and grateful to have been offered a place and hopefully on the programme I’m able to meet a bunch of like-minded people who are as fascinated about the cosmos as me!

Till next time,


Thoughts #8 – On NASA’s Exoplanet Discovery ‘Beyond Our Solar System’

I heard the news that NASA was going to announce a breakthrough discovery a couple of days ago and as an astrophysics enthusiast, I was extremely excited.

Today, 22nd February 2017, NASA announces the discovery of seven new exoplanets orbiting a star – Trappist-1 only 40 light years away. Not only is this a record on its own, the content of the discovery is as or more so intriguing. Yes, we are talking about these as planets that could potentially support life. Each and every one of them are rocky resembling the inner four planets within our solar system – Mercury, Venus, Earth and Mars, and all have been claimed to have the possibility of supporting liquid water on their surfaces. The discovery is not only astonishing in this essence but also of the fact that Trappist-1 is rather small and dim allowing them to be temperate, thus perhaps be home to life.

Even though only three out of seven of the planets lie within the ‘Goldilocks Zone’ of the star system, this discovery opens up more pathways for interstellar exploration into these worlds, enables further research on their atmospheres and gives us a fairly good chance of looking for clues about life out with Earth.
