## Viruses made easy

[P4 - S4 Science & Biology: Micro-organisms & Molecular Genetics] With Covid-19 locking us in our homes, one can't help but wonder what exactly we can do against the virus. Well, it's a good thing that there's media which can help you understand the pandemic on par with adults, isn't it? Enjoy the presentation by renowned physicist and creator of the Mould Effect, Steve Mould:

## Volume of a Cone: Two methods, one answer

[S1 - J1 Maths : Volume of a Pyramid (and for the brave, power sums & integration)] On our last post, we discussed the method which the volume of a sphere is derived. But, for it to work, we need the volume of a cone to work. We have to decisively prove that the volume of a cone is 1/3 x base area x height. Thankfully, if you remember the video from the last post, Cavalieri's Principle states that as long as the base area of the shapes are equal at every point along the heigh
