Visit to the Nanosciences Department at IISC Bangalore

Name of College : CMR National PU college, ITPL, Bangalore Students: I and  II PUC   Our  I and II PUC students visited the Nanosciences Department at IISC Bangalore and interacted with the researchers about different types of on going projects on nano materials. They also collected biological samples from the IISC Campus for viewing…

The last two images is of a Dandelion and a Orange Double Lilly from my backyard.The first two images is from the slides I made of the petals of each while using the Foldscope.Not very clear. My goal is to compare the petals of each.

Magnesium Sulphate – Polarizing movie

For a few pennies, I was able to get some Epsom salts. I added water and let it dry on the slide and then viewed with polarizing filters. Magnesium sulfate is used medically for certain cardiac rhythm problems (Torsades des points), severe asthma, and in certain cases to protect baby when mother enters labor early….

Magnesium Sulphate (Epsom Salt) crystals.

Magnesium sulfate is used medically for certain cardiac rhythm problems (Torsades des points), severe asthma, and in certain cases to protect baby when mother enters labor early. It is also called Epsom salts and used for soaking and skin healing.

Serendipitous Dance of Polarizing Crystals – MgSO4

For a few pennies, I was able to get some Magnesium sulphate. I mixed in water and allowed it to dry on the slide. I thought it had dried, but when I looked at the clip I realized there was a drop of water (at about 7 seconds into the clip) at the top of…

Demonstration of the use of SLIDE A2 (0.5mm GRID) for measurements.

The White sun

Well, we have read that white is the actual color of sun and so today morning hours I observed it at Haldwani,  Uttrakhand. By Abhijeet Singh Dewari from Lakes International School

Bubble wrap under microscope

I saw a bubble wrap under Foldscope and found this, Dont know the exact about the structure but there seem some small air sack like structure . with

Fern spore catapult

I planted a fern in my garden a couple of months ago and ferns have been taking over! I’m not sure about the species — Ostrich fern (Matteuccia orientalis)? I remember learning about fern reproduction involving some strange alternation of generations with ‘spores’ that grow on the underside of leaves. Sure enough, there were a…

Diffraction of light by single slit

I have performed an experiment in physics lab of Kokrajhar Govt. H. S.&M. P. School on diffraction of light by single slit made of two blades. Two blades  are joined length-wise using cellotap with a separation of 1 mm in between. The slit is then placed in position of slide in the Foldscope. Laser(red) is…

A simple hack for reflection/epi-illumination using the foldscope

I have been wanting to post on this for long. There is a very simple way to achieve reflection/epi-illumination microscopy in the new foldscope. For this, I use a simple LED hack that was described by Marie. See https://microcosmos.foldscope.com/?p=13486.  This LED unit can now be inserted from the side as seen in this video. The video…

Fun time with fibres and other things

From the clothes we wear to the paper on which we write, these things are made of fibres. Fibres of polysaccharides. Just how amazing these look under a foldscope…   Paper may look smooth and uniform as viewed from the naked eye, but microscopically a different story is seen.     Cotton fibres seen through…

Happy Birthday, Mr. Carl Zeiss!

On September 11, 2016 the town of Jena, Germany, celebrated the 200th birthday of Mr. Carl Zeiss. I am sharing here some impressions from the personal life of Mr. Carl Zeiss – one of the great pioneers of microscopy – as told through the events of his 200th birthday celebration. Carl Zeiss Jena was originally…

How aperture affects image quality

When I first heard about Foldscope from a friend in 2016 I became curious. Until my Foldscope arrived in early 2018 I started experimenting with ball lens microscopes myself. Please see a photo of some of my models. When I first used my new Foldscope, I was impressed with the good image quality. I attribute…

Capillary action occuring on paper

One thing we often do while preparing any wet mount is removing excess of mounting medium; mainly by making use of blotting paper. Wondered how blotting paper takes up the excess medium so quickly? A phenomenon called capillary action comes into play. Blotting paper consists of several hydrophilic substances and water (most common mounting media)…

Going electronic

Observing this wasn’t planned exactly before, though boredom got the best out of me. Studying for exams were a bit tedious thing… hence this is what I did. Armed with a foldscope, all I could see was my target which was the computer screen, which had all ebooks in it which I was reading at…

Polarized explorations part 2

Hello everyone, There are going to be tons of pics in this post so I better limit the words. I have foldscoped 3 compounds here – Citric acid , L-cysteine and Potassium dichromate. Recrystallized Citric acid Just while I was foldscoping these citric acid crystals an orange caught my attention! I thought Why not try…

Polarized light foldscopy

I finally got myself a polarizing film. By this I can now polarize the light falling on the sample by placing the film between the light source and the sample and further by placing another film between the lens and the eye/camera I can block the same polarized light so that only light whose polarization…

Recrystallization And A Question

Hello Everyone, This time I’ve tried making a time lapse of NaCl getting recrystallized. I have used dark field here to make the crystals look more prominent. Here are the steps I followed: 1. Prepare a saturated solution of NaCl I.e adding NaCl to water till it stops dissolving. 2. Put a drop of this…

Butterfly scales through the lens of a Foldscope

I was really excited to receive a new Foldscope kit recently, and after corresponding with Manu online, we agreed that butterfly scales represent a nice project that others can easily get involved with! Here are some previous posts on the subject: https://microcosmos.foldscope.com/?p=10080, & https://microcosmos.foldscope.com/?p=16562 Here’s magnification of a butterfly eyespot and through the lens of a #Foldscope below,…

Tutorial: Surface imaging using Foldscope – ice formation

I want to start the year with new year spirit. Ice crystals. It’s -26C here; yes – you read it right. Most people are enjoying the fact that it’s colder in Montreal than Antarctica. Something we should be worried about; but that’s for another day. Basic foldscope can be used for surface imaging on translucent…

Inculcating Research Culture Right From Schools

As a part of TIFR, Hyderabad’s efforts to facilitate better science education in the local schools, it now interacts closely with four of the Telangana Social Welfare Residential Schools, all within 10 km from the institute. On regular close interactions with the teachers and students alike from the schools, we realized that schools are fast…
