Guest Guru: Elizabeth Celentano Dishes On Ice Cream!

Hello all! I think there is little else that is more enticing to me than ice cream (OK, I’ll admit it - crème brulee might top it, and realistically it is just a different version of sugary-creamy goodness). So what better scenario could I have this week then being able to make ice cream with my coworkers during a team building exercise?

And the more surprising part? I had 3 experienced, full grown adult, male engineers ask me why salt was needed to make the ice cream.

So, let’s talk science!

First of all, remember that this is when you are making ice cream by hand. Good old hand-crank, churn for long time, until the cream mixture freezes. The salt is required for the ice on the outside of the hand-crank machine.

OK, now back to the why…

Let’s talk about melting and freezing. They actually happen at the same temperature. For example, if I’m a solid and I want to become a liquid, I have to get enough energy (typically in heat form) to raise myself to my melting temperature. If I’m solid ice, I need to get up to about 0 °C. However, getting up to that temperature won’t automatically turn me into liquid (which is why you can still get ice, or snow, on days that are 0 °C). Liquid molecules have much more energy than solid molecules, which is why they are fluid and can’t hold their form. With all the energy required to go into the phase change, there is no temperature change occurring during the phase change.

So what about the salt?

Well, for ice cream, this melting / freezing point is actually at a lower temperature than 0 °C. The sugars and fats in the ice cream mixture require a colder temperature to freeze than pure water molecules would alone. This requires more than just ice to cool the ice cream mixture (otherwise the ice would melt before the ice cream is frozen).

Salt is the key! Salt itself has a much higher melting point than water, so making a salt-water solution will lower the point at which the solution melts!

But, in turn, it’s actually important for the salt-water mixture to melt. Why? Because the energy needed to change the salt-water mixture from solid to liquid needs energy (remember, the phase change we talked about?). That energy comes from the environment. And in what form? Heat. In other words, taking heat from the surroundings to melt the salt-water mixture ultimately makes everything colder, including the ice cream mixture – which needs to be colder than 0°C to freeze.

It’s not magic, it’s SCIENCE! And delicious science at that.

Women in enginnering are super cool

Hello TMG readership!

To my knowledge, I am the first guest-blogger to join the TMG family! I can’t begin to tell you how excited I am to share this space with you all.

My name is Liz. I am a full-time chemical engineer, working in a manufacturing plant. More importantly, I am a lifelong lover of math and science. More accurately, I am a 100% geek. Put whatever you want in front of it – math-geek, science-geek, music-geek, theatre-geek, board game-geek – I am EXTREMELY passionate about a lot of things.

That being said, I wouldn’t have loved math and science as much as I do just from my teachers at school. I was lucky enough to have an amazing tutor outside of school from grade 5 until I graduated high school that went above and beyond the normal school topics. He taught me to LOVE math contests and actually get pretty good at them (did you know you could get medals for MATH?!); he shared his love of astronomy with me (did anyone else see the recent super moon????); but most importantly he would teach me math in a way that made it relevant to me. He taught me that before Pythagoras existed, Ancient Egyptians would use knotted rope to create the right angles needed when building the pyramids using known ratios (later known as Pythagorean Triples). And in an unforgettable moment, he brought this demonstration to my house, and almost got my entire living room wet – but to this day I can recall the formulas for spheres, cones and cylinders without hesitation!

I am hoping through these semi-regular blog posts that I can bring some relevant news or related topics to your attention to help get YOU excited about math and science! I’ll even talk about my work, what I’m getting excited about day-to- day, and I can even answer questions!

Stay tuned, and get excited for this collaboration!!!

Self-Care Tips for Studying

Whether or not you had a valentine this past Valentine’s Day, HOPEFULLY you noticed that it’s MOST important to be your OWN VALENTINE and LOVE YOURSELF! Although we think it’s SUPER important to love and take care of yourself, this can be extremely difficult – especially while studying! Studying can sometimes overwhelm us, stress us out, and completely take over our lives. To avoid having school-life completely take over, it’s important to practice loving yourself by using different self-care tips. By practicing the following 5 self-care tips you will be able to avoid unnecessary school-related breakdowns, you will be able to keep calm and carry on - trust us.

  1. Take a bubble bath

If work is starting to make you go crazy, STOP whatever you’re doing and pour yourself a warm and luxurious bubble bath. Want a TMG trick? Using lavender soaps and Epsom salts in the tub will help to relax the muscles in your mind AND body. Try spending JUST 15 minutes in the bath soaking your body and quieting your mind - that's all it takes, and it makes a huge diff in terms of how you approach your work after giving yourself some soaking time to chill out!

  1. Write in a journal

Get out ALL thoughts clogging your mind and inhibiting you from doing your schoolwork by writing them down. By getting out all your feelings on paper, it will be easier to compartmentalize the thoughts as they continue to flow through your mind. And who knows, maybe now that you’ve written down all your thoughts they might not come back – at least until after you're done focusing on the work you have to do RIGHT now!

  1. Exercise

Exercising is one of the best ways to focus on something other than schoolwork. While running as fast as you can on the treadmill who even has TIME to think about school? Aren’t you just focused on putting one foot in-front of the other and BREATHING to stay ALIVE? Not only does exercising actually rejuvenate you physically, it actually causes your brain to release endorphins which amps up your mood! Science in action guys!

  1. Take the day off

Sometimes you’ve been working SO hard that you just need a day off to do next to nothing. On your day off do NOT even THINK about doing schoolwork. This day off is COMPLETELY for you! Take time to sleep in, stay in your PJ’s and curl up on your sofa with the latest Netflix releases (or like, read a book - FOR FUN). Sounds like the perfect day, right?!

  1. Plan something to look forward to

Sometimes all we can think about is school, school and MORE school. If you have nothing to look forward to besides school, it can be difficult to be optimistic about the future. To make you excited about something other than all of that homework that lies ahead, plan something to look forward to. Whether it’s a smaller outing like a movie with a friend or a bigger excursion like a vacation, planning events (whether big or small) in the future will allow you NOT to ONLY focus on school work; with events planned you will now have other things to think about and motivate you to get work done!

We never said it was easy to take care of yourself. However, we DO know that it’s EXTREMELY important. So, the next time you’re feeling out of control, like the world is going to end if you don’t ace your math test, try implementing one of these many self-care tips - you've got this, we know you do!

How to re-create our vibes at home

It's totally undeniable that the space at TMG has a unique and special vibe. Making you feel right at home with plush sofas and colourful throw pillows, it's almost impossible not to feel super comfy at TMG. From the twinkly lights to the yummy aromatic teas and candles, the vibe at TMG helps students chill out during what can be stressful times. So, my question to you is this: don’t you want these super cool vibes to ALWAYS be surrounding you when doing your homework? If your answer to this question was “YES”, let us take you through the 5 steps needed to re-create TMG's sweet sweet vibes, anytime, anywhere.

  1. Tea

Warming you up from the inside out, tea is a staple at TMG. You don’t need TMG’s crazy tea selection to steep your very own cuppa - although, hey, variety IS the spice of life. We recommend a good chai, a solid flavoured black tea (vanilla, caramel, chocolate...something decadent), a soothing herbal tea (think ginger or lemongrass), and a zen green tea blend. Ask anyone who's savoured our selection, and they'll tell you that the FOAM is what makes the tea. Trust us. Invest in a good frother or go cheap and grab a handheld one!

  1. Candles

Helping to create a cozy atmosphere and making any room smell AMAZING, candles are a TMG signature. Watching a candle burn can be incredibly peaceful and help get you into that super focused study zone. Our fave? The amazingly almost-edible selection found at Bath & Body Works. EVERY season they switch it up so that you can be surrounded by yummy warm scents in the winter, and vibrant tropical scents when the weather gets hot hot hot. So, nestle up with your textbook, light a candle, and get in the zone!

  1. Fairy Lights

Who said that fairy lights HAD to be a seasonal thing? Totally disagree! Making every room both comfortable and bright, fairy lights at TMG are found all-year-round. Ambient lighting can set the mood while avoiding the eyesore that comes with awkward reading lamps and sharp yellow light. Sorry if we’re breaking any classic décor rules but for the purposes of getting in the mood to study in style, this tip RULES.

  1. TMG Apparel

Making you feel like good-luck is always with you, why wouldn’t you want to rock TMG apparel? Comfy, cozy, chic – check, check and check. With items ranging from sweatpants to t-shirts, to necklaces and more, there’s a little TMG for everyone to wear. Oh, and bonus: you get to spread the math-love to anyone and everyone cool enough to notice that you're actually making math math trendy. Go you!

  1. A Positive Attitude

Have you ever noticed that our tutors are ALWAYS looking on the bright side? Whether it’s encouraging you to try your best on a test or re-assuring you that success is just around the corner, we're always trying to lift your spirits and help you gain confidence. So whether you’re at home studying for your next evaluation, or freaking out in class in confusion, try to channel TMG's positive vibes – a little bit of sunshine goes a long way!
