Do all biology students are afraid of mathematics? Do we need to know about all the fundamentals of science? ![IMG-20230616-WA0050](https://metastudio.org/uploads/default/original/2X/8/8783056c6efc7f8a027849863773245e66f4c2c0.jpeg) _Misconceptions Regarding Elementary Aspects of Microscopy and Size_ 🌜Yesterday we came across very elementary aspects of microscopy in the context of _Moina as a model system_@anindita8820 🌛 _Moina ,a freshwater organism_ under crustaceans.Also a Close relative of prawns and crabs​🦐🦀 🌜Cubists are using _milk a feed for Moina_ . @sakshiconsultant2002 @dhanraj7 Milk is a source of energy, such as _glucose which is helpful for the growth and reproduction of bacteria_ . 🌛We came across an interesting question _“How do Moina take bacteria, Do they have eyes” !?_ @anindita8820 's Hypothesis : _Moina do have eyes that may be helpful for them to capture bacteria !!_ ![IMG-20230616-WA0051](https://metastudio.org/uploads/default/original/2X/7/796bb221f38dc0ea50533fd4263fbdf86cdd8040.jpeg) 🌜 _Are we not curious why we are not able to see bacteria in nacked eyes but microscope does !!!_ 🌜 _How do Microscope help us to magnify such small objects !_ @⁨Anindita Mandal Cube⁩ 🌜 Microscope is a _magician_ !!!🤔🤔 According to @⁨Anindita Mandal Cube⁩ bacteria having _0.001µm in size_ . 🌛 _How do we communicate such small sizes to anyone !!!_ 🌜During that discussion most of us @⁨Anindita Mandal Cube⁩ @⁨Smiti⁩ @⁨Khushi⁩ @⁨Aditya Joshi⁩ tried to convert that to m ,cm ,mm & al ._But most us got stuck in certain portions_ . Why we called 10^9, 10^6 like that? What that means !? _Can we go to some flashback stories_ @⁨~Saida Sayyed⁩ @⁨Abhijeet Cube⁩ 🌜When I am discussing my PG project with Cubists last year, _we came across the size of a nanometer !_🦧 ☘Arunan Sir _asked me to explain the nanometer size to a school student 😤_ 🦧I replied that ,sir i know that 1 nm = 10^9 m, Also _i am weak in mathamatics_ 😀 🌛But at the end of the Chatshaala i understood the fundamentals of measures .@⁨Abhijeet Cube⁩ @⁨~Saida Sayyed⁩ 🌜Can we think of the most common instrument that we all can correlate !!!@⁨Anindita Mandal Cube⁩ @⁨Smiti⁩ 🌜Yes _we do have instrumental box & that contains 15cm long ruler_ . ☘If we look _1cm in it , are we seeing 10 divisions on it_ . (1cm =10mm) ☘ _If we split that 1 division, can we get 1000 such divisions_ .(1mm=1000µm ) 1um =0.001mm ☘now are we reach _how small our bacteria is !!!_ ☘Coming to _Microscope ,that is having_ 🌜 _Eye piece 10x_ 🌜 _Objective lens 100x_ Magnification =1000\* ☘ _Magics of microscopy_ ✨Are we seeing 1000 times magnified version of 0.001um-sized bacteria .please share your experience where we got stuck during chatshala discussions. @⁨Anindita Mandal Cube⁩ @⁨Smiti⁩ & others @Smiti @Abhi0703 @anindita8820 @KhushiGupta @saida786110 & others
