https://youtu.be/JaNrMCt9oKg I collected some moss and searched for a few interesting microbes. I found a few and want to share with you my discoveries.
Here I show you how I mounted sand on a microscope slide. This might be an interesting method especially for those people who collect sand samples or those who want to investigate sand for impurities or pollution. A video for Read More …
Water Bears (Tardigrades or Moss Piglets) are animals that can withstand much stress. They can survive high and low temperatures, dryness and also lack of food. I found one of them on a piece of decaying wood, among hundreds of Read More …
https://youtu.be/h7ThRlqXkts Here I compare the size of different cells and also of the Coronavirus to the leg of a fly.
https://youtu.be/HIDjksiwn6c The resolution is determined by the objective of the microscope. For the best image quality, you should therefore use an objective with a high numerical aperture and a low eyepiece magnification.
https://youtu.be/82H_NdjFs_Y These are microscopic worms that I found on a decaying piece of wood. In this video I show you how I isolated them and we will have a closer look into their digestive system.
https://youtu.be/-4HzdclIW3A There are objectives with a conjugate distance of 190mm and those with 185mm. Here I explain the difference. Most 160mm microscopes objectives have a conjugate distance of 195mm.
https://youtu.be/45lJyeCp9SY Here I explain the concept of resolution and why it is theoretically possible (!) too see objects that are below the resolution limit with a light microscope.
I found an insect and now want to figure out if it is a bug or a beetle. We can do this by looking at the mouthparts and also at the structrure of the wing.
The white fuzzy stuff is the mycelium of the mold (fungus). Here I look at the mycelium and also at the spores that the fungus formed. I also compare bright-field images with phase-constrast.
