How does one become a successful engineering student? By studying, I suppose, in order to get good grades in school, and joining clubs, and attending events and workshops. As well, thinking about the future, and making sure everything productive you do can be written into a cover letter or recommendation letter. Then there is learning to network and socialise, and present, and give elevator pitches. And, well, it doesn’t hurt to give good handshakes and own a blazer. Phew. Look at that list. You’ll need at least 72 hours in a day to get through all that.

There is a joke that people make a lot coming into university. “Sleep, social life, good grades. Welcome to university: pick two.” I’ll say this now: there is no guaranteed time-management routine that will help you do everything you want and have to do. There are literally not enough hours in a day. When I look at my agenda today, there are stars next to items that should have already been done. But when I try to set out a schedule that would involve omitting meals, washroom breaks, and sleeping, there are still not enough hours in a day.

So what can you do? You probably didn’t start reading this post to find out there’s no hope left for you. So here’s what I do. I write down all the tasks that I think of but not because I want to do them all. I just don’t want to have to use the brainpower and time I won’t have in order to recall them later. As well, I try to plan every hour of my day so I don’t have to make decisions at a time where I’m running short on energy. But this is not really one-size-fits-all advice.

Instead, I find that the most useful advice to everyone is to be adaptable. Whether that means just accepting that you’ve completely forgotten about an assignment due tomorrow, and you have to start now or else you lose 10% of your grade. Whether that means realising that if you keep up with your perfect routine, you’ll never have time for friends or hobbies or sleeping in. For now, just accept it and do what you think you have to do. If you’re struggling to complete everything, you haven’t necessarily messed up. It probably means you’ve been doing things that you want to do–that is, things that make you happy. And that’s not too bad a trade-off in the grand scheme of things.

When given the option to choose any engineering-related topic for my CCOM206 research paper, I was inclined to write about Taj Mahal—one of the Seven Wonders of the World—since it is located in my homeland, India. My trip to Taj Mahal a decade ago changed my life in ways more than I could have imagined. Though I may not be a desi by personal choice, I am still Indian at heart. I want future generations to also have their breath taken away by the beauty of Taj Mahal, just as mine was when I first saw it.

The first thought that crosses one’s mind when thinking of India is likely the well-known Taj Mahal. This marble-clad mausoleum is considered one of the finest example of Mughal architecture in India. It was built to mark the passionate love of Emperor Shah Jahan for his beloved queen Mumtaj Mahal, after her sudden and tragic death.There is perhaps no better monument which is solely dedicated to love. Every year, over 3 million people come to visit this sacred symbol of love in search of inspiration, and they leave with a warm feeling of awe and admiration.

“A teardrop on the cheek of time” were the words of the Nobel laureate Rabindranath Tagore on Taj Mahal’s flawless symmetry and elegance. In 1983, Taj Mahal achieved the status of an UNESCO World Heritage Site. At that time, it was described as a “universally admired masterpieces of the world’s heritage”; even so, proper care has not been taken to preserve this monument.

Taj Mahal is an engineering marvel of its own kind. The construction of Taj Mahal represented the biggest technical challenge to be overcome by the Mughal builders of that era. As Shah Jahan was adamant about building this monument on the banks of the river Yamuna, the architects and engineers came up with a novel strategy known as “well foundation”. In order to support the considerable load resulting from the mausoleum, the white stone monument was built on hundreds of masonry cylindrical columns sunk into the ground close together. These wells were filled with rubble, iron and mortar—so they essentially acted as augured piles—and were reinforced with ebony wheels at regular intervals along their lengths. Ebony was used, as it is dense enough to sink in water and also has an infinite life-time in water.

Recently, a startling discovery has taken over the front page of all newspapers in India—Taj Mahal, the famous epitome of love, is starting to sink. The news that Taj Mahal is going to collapse in the next five years came during its 350^th anniversary celebration. Shah Jahan is not to be blamed because when he commissioned to build Taj Mahal, he got everything right: from the design, to its science. He neither stinted on the ebony which props up the Taj, nor did he anticipate the Yamuna going dry. But even the finest ebony in the world needs a steady stream of moisture to ensure it does not expand or contract, both of which pose a grave threat to the structure.

In the past decade or so, the ‘perennial’ river has been completely drying up in the summer months in Agra, posing a potent threat to India’s most famous monument. Experts say a dry Yamuna could play havoc with the Taj’s foundation, making a solid marble love story wobbly at the base. The pressure of the river flowing by Taj has kept the building erect. But the building is no longer getting enough support due to the evaporating Yamuna River, and cracks have started to appear on Taj’s veneering marble slabs. Also, research shows that the south-west minaret has tilted by about 8.5 inches—this is quite a lot!

Taj Mahal is part and parcel of India’s identity and as such, Taj must be preserved. River restoration projects such as the Yamuna Action Plan (YAP) have been implemented but not yet found to be effective. As the situation grows increasingly dire, the Archaeological Survey of India (ASI) should take immediate measures to intervene. Otherwise, we might as well say goodbye to this three–and-a-half centuries-old monument.

In 1850, William Gladstone asked the scientist Michael Faraday why electricity was valuable. Faraday answered, “One day, sir, you may tax it.”

Indeed, electricity has become such a fundamental part of modern society. We use it for almost everything we do: from lighting up this classroom, to charging our phones, to sharing this powerpoint presentation with you.

But what many fail to see is that the generation of electricity has become so widespread that its environmental impact is simply not negligible anymore. Most electricity today is generated at power plants that convert some other kind of energy into electrical power. Each system has advantages and disadvantages, but ultimately, many of them pose environmental concerns.

Indeed, the majority of our electricity production is based on burning fossil fuels to produce steam, which is then used to drive a turbine that, in turn, drives an electrical generator.  In addition to being harmful to the environment, these are non-renewable and limited sources of energy on earth, so we must consume electricity in a conscientious and sustainable way in order to ensure our energy supply in the long term – for ourselves but also for future generations. Additionally, as Faraday predicted, electricity, and most importantly energy, is not free. The electricity bills add up, and the longer we leave our lights turned on for nothing, the more money we waste.

Hence, even a small amount of saved electricity can have a large positive impact on our environment, and at McGill in particular.

So what’s the solution? Taking it one step at a time. Starting small. The goal is to promote sustainability at McGill, and we can do so by installing automatic, motion sensor lighting in as many campus buildings as possible. The Schulich Library has already jumped onto the energy-saving bandwagon by installing such automatic lighting, but many buildings have yet to catch up, such as the Birks building.

McGill’s Birks building comprises four floors and is mostly used by the facilities staff and students of McGill University. It consists of classrooms, offices, hallways, staircases, a library and washrooms, as well as a chapel. The lights in the building are kept on for around 10 to 12 hours per day, 5 days a week.

Ultimately, these lights do not need to be turned on consistently for that entire period of time whilst a classroom is not in use, or whilst a staff member is not in his/her office. Similarly, lights in the staircases need not to be switched on when not in use. We have consulted with students and staff of the building and they informed us that the lights remain turned on in between classes, and are only rarely switched off if someone walks by and notices. Likewise, lights in the washrooms are kept on for a stretch of 10 to 12 hours per day even when they are not in use, ultimately resulting in an evident loss of energy.

Moreover, even smaller instances that we look over also have an impact on the consumption of energy. For instance, staff working in their offices may forget to turn off their lights before leaving for lunch. Furthermore, a massive amount is spent on lighting up the library and the staircases alone due to their sheer size.

Therefore, I believe that the installation of motion sensor lighting is the solution to all the problems mentioned above. After using the equation E = P*t, one can calculate that motion sensor automatic lighting can save an estimated 23,351 kWh of electrical energy per year – about 50% of its total energy consumption – as well as over $1,400 per year, assuming that electricity costs 6 cents per kWh.

Perhaps it is worth looking into… saving the planet is ultimately done one step at a time!
