سرگرمیهای فیزیک در اینستاگرام

فیزیک جادوی واقعی جهان را توصیف می کند.

دوران مدرسه رابطه خوبی با فیزیک نداشتم، چون بر خلاف ریاضی اصلا برام ملموس و هیجان انگیز نبود. شاید اگر اون موقع با آزمایشهای سرگرم کننده فیزیک مواجه میشدم، به فیزیک هم علاقه مند میشدم. امروز با حساب اینستاگرامی «سرگرمیهای فیزیک» آشنا شدم، و یکی دو ساعتی سرگرم شدم. سعی میکنم بعدا بعضی از ترفندهای ساده اش رو برام پسرم اجرا کنم، مثلا این:

Ring Catch Chain Trick: a solid ring will be caught by a loop of chain if it tumbles during its fall. By Newton's Third law, when the ring twists into and hits the chain, the impact transfers momentum to the end of the chain, which rises up and over the ring- seen here at about 6x slow motion. ➡️ Follow the link in my profile for info on where to get this device and other amazing items featured here on @physicsfun #kineticenergy #torque #physics #physicstoy #physicsfun #angularmomentum #centerofmass #symmetry #ring #ringchain #science #scienceisawesome

مواردی رو هم تحت عنوان غیر ممکن آورده که اونها هم میتونن تا مدتها ذهن رو به خودش مشغول میکنه، مثلا این:

Impossible Pipe Elbows: made from standard pipe fittings held together only by their threads. One more “impossible” object recently added to my collection. No glue of any kind was used in its making. Design inspired by puzzle maker and artist Saul Bobroff. ➡️ Follow the link in my profile for info on where to get “impossible” objects and other amazing items featured here on @physicsfun #mechanics #physics #physicsfun #engineering #STEM #machanicalengineering #puzzle #impossiblebottle #impossibleobject #science #scienceisawesome

Impossible Nail: An eighteen-penny nail driven through the inner notches of a solid piece of wood. The wood was notched and the nail added- no glue used or cuts made, and the nail is solid and in one piece. Not impossible, but creating this does depend on the use of some amazing physical properties of wood. I won’t reveal the method here but a quick search on YouTube produces a few how-to videos showing the process. The nice version of this puzzle featured here is from @emvz.creations ➡️ Follow the link in my profile for info on where to buy this and other amazing items featured here on @physicsfun #mechanics #physics #physicsfun #engineering #STEM #machanicalengineering #puzzle #impossiblebottle #impossiblenail #impossibleobject #science #scienceisawesome
