Throughout A Journey into Modern Physics, third party videos were recommended to produce additional information. Here they are.

IMAGE WALL - 1
You will find images on this wall associated with A Journey into Modern Physics.
To get the most out of the images, use zoom and pan facilities on your device to navigate around the picture where there is lots of detail.
Presented here are two of the diagrams that were used in Part 1 to categorise sub-atomic particles.
IMAGE WALL - 2
In chapter 7 of part 2, the life history of stars is presented. The following flow diagram was used to illustrate the sequences from birth of a star to its end. This diagram was not used in the LIGHT adaptation of part 2, due to size constraints. Chapter 7, in both series, contains detailed descriptions.
IMAGE WALL - 3
Chapter 4 in part1, described the way in which electrons populate atoms from hydrogen onwards, to create all the elements in the periodic table.
Each electron fills the next empty, or partially populated lobe when an atom is constructed. The sequence from hydrogen to Calcium is shown here in the figure 4.6 used in Part 1.
IMAGE WALL - 4
In this diagram, elements from potassium to the noble gas krypton are shown. Each row corresponds to a single element, listed on the left.
The table below shows how the d3 orbitals are ignored until scandium and are only filled at copper after the s4 level has been depopulated.This unexpected sequencing of orbitals is all to do with the energy levels of the empty d3 set being above that of the s4 orbital. The energy levels of the d3 orbitals settle down and fill up eventually
All is explained in chapter 4 of Part 1.

Ever wondered how the size of an EM wave's wavelength compares with normal every-day objects? What is comparable to a gamma ray's wavelength, for example? Here's a table from chapter 3 that might help.
On the left is a depiction of a nucleus that was used in chapter 1 of the book series.
It gives the impression that nuclei are random collections of protons and neutrons. Nothing could be further from the truth. Nucleons exist
in shells, just like electrons in atoms and are described with probability functions. But as the nuclear force is very short range, nuclei are dense, highly organised structures.

One of Einsteins's thought experiments: Finding yourself in a closed box, standing on the surface of the earth is exactly equivalent to being in a rocket propelled box in outer space, far from any gravitational field, when the rocket is accelerating at 1g. The 2 situations are equivalent.
If space person aims a laser at a target on the wall, because the rocket wall is moving upwards, the horizontal beam lands just below the target. If the equivalence principle, from thought experiment 1 is correct, the same happens on earth - gravity bends light.
