I love flying lobsters

ha! they do look like lobsters

Hello I can’t decide whether I want to be a lobster, a moth, a butterfly or a hummingbird???

• Accidentally close a tab? Ctrl+Shift+T reopens it.
• Bananas release dopamine, eat them when you’re sad.
• CTRL+SHIFT+ESC is the one handed version of CTRL+ALT+DEL
• Don’t brush your teeth hard, it makes them sensitive and removes enamel.
• Don’t like spiders? Put citronella oil on your walls and they will not go there.
• Drink one glass of water for every alcoholic drink you have, you’ll get drunk without getting a hangover.
• Get clear ice cubes by boiling water before freezing it
• Heal paper cuts and immediately stop the pain with chapstick.
• If you accidentally write on your dry erase board with a permanent marker, scribble over it with a dry eraser marker to remove it.
• If your shoes smell, put them in the freezer overnight, it will kill the bacteria.
• Make bug bites stop itching with a banana peel.
• Make a paper longer with 12-point text, but 14-point periods and commas.
• Need to get around a blocked website at work? Try replacing the http:// with https://
• Never send your resume as a word file (unless asked) Instead, print it to a pdf file, it’s much cleaner and professional looking.
• Pick a flavor of gum you don’t normally chew, and chew it while studying during a test.
• Place a piece of bread in a container with your homemade cookies and they will stay soft.
• Put a dry towel into a dryer with wet clothes, they will dry faster.
• Put toothpaste on a pimple and it will dry out.
• Practise fake smiling in the mirror every day before going to work/school, you’ll genuinely start to feel happier.
• Rub canola/olive oil on knives before cutting onions, you won’t cry, alternatively chew gum and you won’t either.
• Short on time with a wrinkled dress shirt? Hang it up in the bathroom to steam it flat.
• The night before, place things you don’t want to forget the next morning on top of your shoes.
• Use hydrogen peroxide to remove blood stains from clothing.
• When cleaning windows use newspapers or coffee filters instead of paper towels, they will not leave streaks.
• When microwaving bread products/pizza put a glass of water in with it, it will keep your bread for going spongy.
• When you move into a new place you’re renting, take pictures of any and all damage, then post them on facebook (privately if preferred) so you can use the reference date as proof you didn’t do it.
• When searching plane tickets online delete your cookies prior, prices go up when you visit a site multiple times.

Standing waves (aka stationary waves)

Standing waves are an interesting physical phenomenon that show up in several places in nature. They’re a wave that oscillates “in place”.

One of the ways a standing wave can be created is by the interference of two waves travelling in opposite directions (like in the second image). By the superposition principle, the resulting wave (in black) is the addition of the both waves (red and blue).

This standing wave has points that remain fixed (called nodes, in red), where destructive interference always occurs, and points that oscillate the most (called antinodes), where constructive interference occurs.

Standing waves are behind the sound of virtually every acoustic musical instrument, whether it is a drum, a flute or a violin. The musician operates the instrument in a manner to generate a vibration, and the vibration is propagated and reflected throughout the instrument. The interference between all of the reflected waves generate standing waves, which is what ultimately produce the bulk of the sound we hear.

The waves shown here are one-dimensional, but this phenomenon occurs in two and three dimensions as well.

By studying how waves interfere and reflect, and how these generate standing waves, one can estimate the vibration and density inside a spherical body (such as the Sun or the Earth — read those links!) from measurements of oscillation on the surface, a very powerful tool for studying the inner workings of such structures.

In the third animation, for reference, we see the wave generated when opposing waves of different frequencies interfere.
