Lab: Refractive index and sugar concentration in water

A physics lab in which I conducted my own experiment, seeking to answer the following question.

How does sugar concentration in water affect the refractive index of the solution?

Singularities, black holes, and the geometry of space

Singularities: An answer to a theory of everything Edwin Hubble (along with others) discovered that the universe is expanding. He absorbed that the majority of galaxies where moving away from us from its spectrum. Its spectrum appeared to be redshifted: when the light wave expands when the source of light moves away, thus moving the wavelength of light towards the red end of the spectrum. We know that if the universe expands, if we reverse time, the universe must have been smaller. And some long ago, the universe would have been the size of a dot. It would have infinite mass and density and would be extremely hot enough pull apart not just atoms nor nucleuses, but elementary particles and quarks of which we don’t know its components. This singularity would live in a single dimension, just a point in ‘space’ (in fact this point is space). We learn that this singularity might lead us a key of the universe. However, this isn’t the only singularity we can find in space or in time. ...

Battery power - a potential victim of temperature?

A write up of a lab in which I researched and conducted an experiment to answer the following question, in order to reveal the implications of how temperature can affect batteries. How does temperature exposure affect the electric power of a Ni-Cd battery? Link to PDF of paper

The effects of new knowledge

I have selected three objects/entities that I will use as evidence to answer the following question (courtesy of the International Baccalaureate Organization for creating this question for the Theory of Knowledge class). Can new knowledge change established values or beliefs? - Object 1: Image of the cosmic microwave background radiation This is an image of the cosmic microwave background radiation (CMBR), the electromagnetic radiation which is remnant from the earliest stage of the universe; the image has also been my go-to computer background. The CMBR’s discovery in 1965 effectively confirmed the Big Bang theory of the universe’s origins, which is why it interests me as someone who passions cosmology. However, before its discovery, it was the established belief both in the realm of science as well as in religion that the universe had been in existence for eternity. The Big Bang theory simply was not compatible with the beliefs of the larger portion of religious sects; for...
