Fulbright scholar Dr. Praveen Pathak conducted a physics with phones session at Saturday's PTSOS workshop. He shared his add-on experiment to @phyphox.org that calibrates the acceleration and integrates to find velocity and position. You can install it using the QR code below. #ITeachPhysics

Rich people more likely to steal children’s sweets, finds Ig Nobel prize-winning study
We round up this year’s winners at awards for achievements that ‘first make people laugh and then make them think’ It’s that time of year again: a select group of scientists have been summoned to a ceremony to receive coveted prizes, be showered in paper planes, and leave with a 10tn dollar bill, albeit in the form of a phased-out note from Zimbabwe. It is, of course, the annual Ig Nobel awards. Not to be confused with the more prestigious and career-changing Nobel prizes that will be announced in Scandinavia next month, the satirical Ig Nobels are awarded for achievements that “first make people laugh and then make them think”.

So happy with the registrations for our 10y conference - this will be a truely international conference. We have fixed the program: phyphox.org/10y-conference If you have not yet registered because you did not know what the program would offer: We extended registration until the end of August
A world map with highlighted countries, overlayed with the phyphox 10y anniversary logo  and the text "The conference - registration open until 31st August". The highlighted countries cover most of Europe. Additionally Morocco, India and Japan are highlighted. Color scheme of the map reflects the typical phyphox colors: Dark, near black background, slightly brighter countries with white outlines, highlighted countries in orange.

The FIFA Prize for Literature 

Following the success of their Peace Prize, FIFA establishes a literary prize judged by the footballers at the world cup. 

(image of trophy)
 
 All does not go well...
 
Players arrive at games exhausted by reading hundreds of novels and heatedly debating their merits long into the night. 

(image of tired players on pitch reading)

The south American teams boycott the tournament when an official disparages Isabel Allende's use of magic realism. 

(Image of players angrily leaving)

Seventeen plavers receive red cards after a discussion of radical honesty in the works of Karl Ove Knausgaard turns into a brawl. 

(Image of players fighting)

However, all is forgiven as Joyce Carol Oates takes the thrilling final to extra time, before losing on penalties to Haruki Murukami.

Our new paper "Real-time camera experiments with phyphox" has just been published at "Physics Education". iopscience.iop.org/article/10.1...
The photo shows the experimental setup from one section of the paper. It shows a close-up of the upper part of the screen of an iPhone with the user interface of phyphox in the front. The interface shows some data, which is not entirely in the frame. To the left of the phone, a blurry red fidget spinner is visible. It is out of focus in the background and shows motion blur from rotating. The phone is oriented towards the fidget spinner, so it can see it with its camera.

A purple equilateral triangle shared a vertex with the hexagon, and has another vertex on the line across the hexagon’s middle. A blue line from the third vertex of the triangle joins to the next vertex of the hexagon to make an unknown angle with the side of the hexagon.
