Earlier this July, my childhood dream finally came true. Over the series’ 20 year history, I’ve played more than 30 Pokemon video games, and with each new release I’ve wanted to become a gym leader and to catch ‘em all – a feat I accomplished, once, back in the first game. Now, as a 28-year old working on a Ph.D., I can finally achieve my dream with the help of Niantic’s latest augmented reality game, Pokemon GO.
I can find a Pidgey (the Pigeon Pokemon) on a city sidewalk thanks to GPS telling Pokemon GO where I am. Finding a Goldeen (the Goldfish Pokemon) on the same city street would not make sense.
In Pokemon GO, as I wander around my city, my phone periodically vibrates indicating that I’ve found a Pokemon. I quickly look at my phone and tap on the Pokemon to enter a battle with it. The game knows where I am thanks to GPS, the Global Positioning System, and uses that information to show me location-appropriate Pokemon, such as Water-type Pokemon close to rivers and Fire-type Pokemon in deserts.
In Robert Zemeckis’ “Back to the Future,” Doc can toss garbage straight into the engine to power his car.
“New innovation from scientists,” read the subject line from my Mom’s email. Attached was a link to a Youtube clip of a male scientist balling plastic bags, sealing them in a steel vessel, and pushing a button. After a couple of hours, the eager scientist cracked open the vessel, and poured out a dark, ominous looking fluid. “People don’t know that garbage can be made into gasoline” the scientist beamed. Apparently after some refining, this scientist had converted plastic bags into gasoline.
My response was immediate: “Don’t go investing your money just yet. Plastic bags are a by-product of gasoline production. It would take a lot of energy to turn plastic bags back into gasoline, probably more energy than you would make.” I had put the thought out of my head, until one day when I was breezing through a fashion magazine (yes, some scientists read those too) and there was a short article about another woman who was also claiming she could turn plastic bags into gasoline. The idea was obviously gaining momentum. Could my opinion on trash-to-gas be jaded?
Ever since ancient Greece, man has been enticed with the idea of being invisible. Our stories offer different paths to achieve this invisibility – for example, Plato’s shepherd became the King of Lydia with the help of a ring which makes the wearer invisible, and H.G. Wells’ The Invisible man becomes so by drinking a formula he invents.
The popularity of Harry Potter, however, has caused this power to take the form of a cloak in our imaginations. How simple it would be to cover ourselves with a piece of cloth that makes us invisible! Every time you are put in the spotlight against your wishes, made to answer an awkward question or want to be undisturbed, you just slip a cloak over yourself and you’re invisible!
Now our governments are apparently willing to spend money on making this crazy dream come true. Different research groups around the world have come up with different ideas to make this a reality. Though they are all in incipient stages, there seems to be a lot of potential in these ideas. Now we look at a few of these brilliantly crazy ideas. Continue reading
