How to Manage Your Time as an Engineering Major

Hey engineers!

I’m so excited you guys picked an engineering major! I know it’s hard to manage time but that’s why I’m here! Just in case you don’t think I’m qualified to teach you about time management I’m a rising sophomore majoring in mechanical engineering, minoring in biomedical engineering, I’m on a biomedical design team, public relations officer of the Undergraduate Biomedical Engineering Society (UBES), vice president of Engineering World Health, a sister of Alpha Omega Epsilon, and a mentor in Hypatia and I still managed to have a good GPA. So without further ado I present to you my tips and tricks to getting the most of your college experience as an engineer.

Be organized

 Hopefully this one came to mind already. Color code all of your subjects. Make specific folders on your computer for the semester and the classes in it. 99% of your homework will be online so it’s important to be able to go back and find an old assignment quickly. This is how my folders are organized.

This goes for your email subjects too. My foundations group member (and now best friend) is infamous for sending out emails and files with weird names. How am I supposed to know which file is for which event? I mean just look at the emails she’s sent me.

Note how most of those emails have tags on them. This is extremely important if you want to find things easily. Most of the time random people will be emailing you and you might not remember who sent you what. You can search their email address but this way is foolproof. It also allows you to realize what is trash and what you should keep. Personally, I keep all my scholar receipts and any important updates or events that are sent to me. Everything else goes. Even with this policy I managed to rack up over 1,300 emails this year. Stay on top of your email people!

Also, go out and buy yourself a really solid planner. I know some people like google calendars and that’s fine but personally I’m more of a paper and pencil person (plus if a teacher says a deadline in class are you really about to whip out your phone in class and enter that in your calendar? I don’t think so).

In high school I would simply write assignments on the day they were assigned to me and it was super easy to stay organized. THIS IS NOT THE CASE IN COLLEGE! You’ve got 18 credits to juggle, meetings to go to, events to plan, etc. When someone gives you a date write the assignment down on the date that it’s due. When you finish that assignment cross it off on your planner. This way you don’t have to stress about forgetting something. Just look at your planner and if everything is crossed off for tomorrow then you’re in the clear. I have never missed a due date or event using this method.

Prioritize

Another reason the planner method is a personal favorite of mine is for prioritizing. Maybe you have a huge essay due Friday but what about that chem lab on Tuesday? The essay is bigger but the deadline for the lab is sooner. Do the thing that’s due sooner. Alternatively, don’t slack on an essay due in two days to do some bs homework assignment due next week. Seeing the day things are due directly on your planner should help you avoid that.

Not only is this good practice for assignments but also for events and just having fun! If you can see that the next assignment you have to do isn’t due until next week you won’t feel guilty or stress about going to a party or just hanging out with friends. However this brings me to the next topic…

Fight the FOMO (fear of missing out)!

One thing that does suck about being an engineer is being surrounded by non-engineers. Not that their classes aren’t challenging, but typically they will have much more free time than you will. It’s important to realize that it’s not you slacking off that’s creating this gap. The sooner you realize this the better off you’ll be. You simply have to work harder than them to maintain a decent GPA. Remember this when all your non-engineering friends are going out to party and you’re stuck at home studying for those dreaded Friday night physics tests. I know it’s tempting to go out but trust me, you’re not missing much. In the long run you’re going to make more money than they will… Like my mom says, “you’ll be laughing all the way to the bank.”


Erase that doubt

 There will come a time when you’ll doubt if you’re really meant to be doing this major. Fight it! Remind yourself why you want to be in this field in the first place. Imagine how sucky your life would be without engineering. Drive yourself to change the world with your talents! Have confidence that you can do all of the activities you want and still get good grades. I did! Look at all of the amazing things I was able to do and still get good grades. I know you can too!


Destressers 

When things become just a little too stressful (this will happen to you at least once) you need to have a game plan. Have music or a show on the ready in case you start to get overwhelmed. Personally, I play with rubiks cubes or go for aimless walks when I begin to panic. I’ve discovered a lot of the Blacksburg area from these walks. Just give yourself a breather and come back to your work when you’re mentally ready to. Even if you waste an hour or two that’s just a small price to pay in sleep to take care of your mental health. Spring semester I went an entire month where I was lucky to get 4 hours of sleep per night. Even though it was exhausting I would do it all over again in a heartbeat. There’s nothing else I’d rather do with my life and there’s no better place than Blacksburg!

I hope some of these helped you guys and if you ever have any questions don’t be afraid to ask me! I know you guys can do it!

Mathematical Model for Robots with ‘Bacterial Brains’

A Virginia Tech scientist used a mathematical model to demonstrate that bacteria can control the behavior of an inanimate device like a robot.

The research is in Scientific Reports. (full open access)

mr-dvorak asked:

Would it be possible to have a solar system like ours, but with a large planet in the center instead of a star?

Well, first off we can make a guess by the language we use - Solar System. Solar; pertaining to the sun (or Stars). 

I personally don’t know of any solar systems with planets at the centre (would they be called planetary systems?). The reason for this, is that most of the more massive planets are made of gas anyway, such as Jupiter. Once masses of gas get to a certain level of mass, they began the fusion process due to the sufficient gravity and ignite into a star anyway. So it’s a no-no for gas planets, as they’ll just turn into stars.

For rocky planets, it’d take much more mass to create ignition. But the largest rocky planet we know of is Kepler 10c, around 17 times the mass of Earth - nothing compared to stars (generally). 

With a lot more free particles and gases such as hydrogen drifitng in space, it’s intuitively more common to see large gas based planets, as they have the building material. Much less common to see more complex material such as rocks. Plus, planets that are gas and planets that are rock tend to form in slightly different ways; but you’ll need to go get a physics degree for that!

So this will be a science answer - no, it’s not really possible with the knowledge of astronomy we have now. But the fact is we know so little about space and i’m sure this could be proven wrong. 

But the thing is, stars are massive. The Sun is a million times larger than the Earth, and it is just a medium sized star. We know of others much bigger. By contrast, Kepler 10c is the biggest (rocky planet) we know of, and it’s not crazy different than Earth. 

Another thing to keep in mind, there are binary systems with two stars, as well as systems that are around black holes. I’m sure this could create the perfect circumstances to have a planet at a particular “centre”. Also remembering that solar systems orbit other parts of space etc, and that everything is moving all of the damn time. Orbits are just a construct for predictions and understanding in a particular reference frame, and are just a direct consequence of gravity. 

Gravity isn’t picky about what it attracts to, it just knows it attracts to the bigger things stronger.  

As always, science answers suck because they’re so not definitive but so definitive at the same time! Hope it helps get you thinking though.

anonymous asked:

So, I'm trying to write a book that takes place in a different world. Small detail: in this world there's a very bright star, kind of a second sun. I have very little idea how orbital patterns work. Can I make it visible both at night and in the day? Can I make it always due south? Would it rise and set, or stay in one place? I'd be hugely grateful for any light you could shed on the matter (heh. heh. light.)

Hmm, I guess I have a couple of things to think about:

1) When you a say a second Sun, there would be an issue with seeing it both night and day. Firstly, night is just a word to describe the point at which a particular side of the Earth isn’t facing the sun. So a second Sun? There would be no night time if we assume “a second Sun” means a star close enough to the planet for it to be large and not just a distant point of light. So bear in mind, the bigger (or closer) the star at night, the more light there would be from it.

2) You can make stars always due a certain point. Think of the North star in the northern hemisphere, or the Southern cross in the southern hemisphere. Sure they move in the sky slightly as we orbit the Sun, but they are still in the same general direction. Again, keeping in mind these stars are light years away and that their orbital patterns have nothing to do with ours. We only have one star that mainly affects us, being the Sun. 

Also lets think of the moon. From here on Earth, we always see the same face of the moon right? It’s basically in a strange equilibrium where it spins about its axis and orbits the Earth at a perfect amount that pairs with the Earths orbit and revolutions, that the same side (generally) faces the Earth. So that’s something to ponder on. 

3) Look into Binary systems. Pluto and Charon are a binary system. In fact, the Earth and the moon is a binary system; albeit to a lesser degree. It’s where two objects in space have particular gravitational interactions, that they orbit about a kind of “center of mass”, as opposed to one orbiting the other. 

I feel like this hasn’t been much of a help. But I’ve gone off some limited info. So please don’t hesitate to send me other messages when you have a more detailed idea of what you’re trying to do.

My last bit of advice is just to look up basically how orbits move and work, such as why things rise and set, why there is night and day, and particularly look up the things I mentioned. If you look up the North star, Binary Systems, and the fact that the moon always has a same side facing the Earth, you should be off to a good start.

Meili & Peter - Mursteg footbridge, Murau 1995. Initially built as part of a timber construction exhibition, the bridge allows pedestrians and cyclists to traverse the Mur river, crossing the body of water and compensating for multiple elevations on each bank through four separate entries. The entire bridge envelope is actually a large scale Vierendeel girder, which unlike a traditional truss that relies on diagonal connections, allows for large rectangular openings. The walls adjacent to the entries of the bridge act as the vertical transverse stiffeners, and the roof and platform serve as the bottom and top chords. This strategy allows for a large opening in the center of the bridge, creating a beautiful picture window that captures the river and surrounding town. These vertical members are also slightly staggered in plan, ensuring that there is diagonal sheer strength while also forming separate circulation pathways for pedestrians and cyclists.  

While a traditional Vierendeel girder is constructed with steel, the Mursteg bridge is constructed almost entirely of wood, creating an unprecedented set of technical complications. Each timber element is fastened with a unique method in order to support the structural forces within; the top and bottom chords are made of pneumatically pressed glue laminated wood planks assembled in pieces, which were connected on site with an epoxy glue. The vertical sheer walls were similarly glue-lammed, but then reinforced with a dense nailing pattern. A post-tensioned cable was installed on the lower chord; and in tandem with the dead-weight of the roof, stiffens the entire structure. The complex engineering performed by the architects in conjunction with Jürg Conzett and Kaufmann Holzbau results in a deceivingly simple and beautiful landmark for the town, in which the spatial design is a direct manifestation and expression of the inherent structural properties of timber.

Figuring Out How to Fold Solar Panels, Airplane Wings

The art of paper-folding called origami can produce complex shapes that are both beautiful and useful. It is being used to understand how DNA works, to make powerful microscopes out of paper, and to improve architecture and medicine

But if you want to convert something flat into another shape to reduce its size for packing and shipping, origami folds need to get even more complex for thicker objects. How, for instance, would you fold a space mirror for delivery into orbit or a new generation of retracting roofs, shape-shifting airplane wings or solar panels?

The answer, according to researchers at Oxford and China’s Tianjin University, is that you need to add hinges, extra material and crease offsets to produce origami’s smart folds in thick objects. Learn more and see more images below.
