Amazingly cool I love it                     Amazing DJ YAN-T

Probably kind of obscure for non scientists but really enlightening for interferometry                     Very cool Tais_Afinskaya

stupid     horrible Nsfbbsjxido

It s neat                     cool zumasandy

I hate this game I thought that stuff would pop out of your phone but all it is is colors I think this would be tons of fun if you were two I don t like this app at all     This game is AWESOME NOT Math wiz 27

This is really boring and stupid     Boring SR18901

Stupid I thought it would be fun but no don t buy or get it people     Stupid Aralina Annamoon

this is awesome it s a bit hard to understand how the patterns colors relate to physical reality does color represent phase but it s easy to use and very pretty                 pretty sweet expert mouser

I think it is really fun to see what happens when you move the balls eliminate and add more and make them bigger and smaller So not dumb                     Dumb I don t think so Energetic2

What do you get when you combined lame and boring ding ding ding This app     Hate it Dragon ninja679

Can t figure out what angle you hold your phone at         What angle do you hold your phone turnerfour

We re just like on a dif Planet                     OMG Sxe Me

Cool app I like it but it s not boring it s addictive                     Zeesbff xiandy

This is an app created to physically manipulate molecules using so called optical tweezers said tweezers having been invented by the current US Secretary of Energy Steven Chu garnering him the Nobel Prize in Physics You won t be tweezing any molecules with this app since you re likely lacking the few hundred thousand dollars worth of peripherals needed but you can explore a bit about zone plates moire patterns and holography The round balls on the screen are what you use to manipulate the colored pattern on the screen You banish a ball by double tapping it You make a new ball appear by double tapping the screen background Start out by banishing two balls Now manipulate the ball that s left Move it off center so it is in the right quadrant left quadrant if you re a lefty You ll see a bunch of straight bands or stripes Now start growing the ball by putting two fingers in it and pulling them apart You ll see that the colored bands bend and eventually become concentric circles around a large open center Note that the bands get closer and closer together as the rings go outward This object is called a zone plate and it is a naturally occuring fundamental wave form Drop a stone in a still pond and you ll see this exact same shape with the waves getting closer and closer together Drop a boat in a still lake and you ll see the same thing Start moving the boat and you ll get a series of concentric rings Move the boat fast enough and the boat will outrun its own rings In that case the rings build up in front of it pushed by the boat and then trail off to the sides what we call a wake Some thing with aircraft but in their case the rings are sound waves Outrun sound and you ll get a wake just like the one from the boat People on the ground experience the wake as it passes over them as a single loud boom a sonic boom Tsunamis tidal waves are also zone plates their energy racing outward in ever more compressed rings Holograms consist of millions of zone plates each eminating from a single point of light Look at a photographic hologram and you ll see many large zone plates Those are coming from dust particles very close to the film The objects further away have their lines so close together you can t perceive them with the naked eye This app was designed to generate holograms that are used to aim lasers at nano sized objects to manipulate them hence optical tweezers Now stretch the ball out much farther until it is taking up much of the screen Notice how some phantom zone plates appear toward the top and bottom of the screen The bands are interfering with the pixels making up the screen Television suffers from this Personalities are warned not to wear certain kinds of stripes and checks or they can interfere with the pixels in the camera causing what s called strobing These patterns are called moir patterns You see them in certain materials like silk or rayon when multiple layers overlap Stretch the control ball further until it is larger than the screen More and more zone plates will appear Note the spaces between the zone plates Now there are many phantom zone plates representing places where the bands of two plates are either both present or both absent If this were water the spots where both are present would have uncharacteristically high waves and where both absent would have uncharacteristically deep troughs Rogue waves those up to 200 foot high collosal waves capable of sinking a large modern cruise ship arise from just this sort of interference Keep going and the screen will be completely filled with little balls Expand it further and every so often a new large pattern will appear When two layers of material have the same pattern and you rotate them against each other you get a magnification of the underlying pattern Try this with semi transparent fabrics or window screening material Now get rid of that control ball by double pressing it The screen goes black No it hasn t crashed Double press again and you ll get a new ball Now slightly enlarge it and start twisting it You ll see the color pattern begin to twist as well Keep most of the control ball off the screen so it doesn t cover up and mute the pretty pattern again and keep twisting Then make the colored spiral spin by pinching and stretching the control ball Now you re on your own                 Zone plates moir patterns and more Asktog

Fun easy to figure out and it s ingenious                 Love it KoolDaddio

0 o Oo Bunny approves                     I love it it s so amusing lol Maggie McDonald

I dont get it     Fu Ufo111

You can make really cool looking designs easily you don t learn about holograms and the twisting control on the dots is a bit annoying because the dots are almost impossible to make them fracture the light but I think it s still cool                 Cool looking Endrika
