How efficient can a rocket engine be?

Let's say we have some mass of propellant m. We can release ALL the energy of this mass as according to mc^2, in some kind of perfect fusion or antimatter reaction. The burned mass is m_b and the unburned mass, into which we dump all the energy from the burned mass as kinetic energy, is m_u.

So
m_u + m_b = m

Relativistic kinetic energy is
KE = (γ-1) m_u c^2

We put all the burned mass's energy into this, giving
KE = m_b c^2.

We have the expression for relativistic momentum,
p = γ m_u v
where v is the exhaust velocity of the fuel.

The Lorentz factor γ is
γ = (1 - (v/c)^2)^-(1/2).

We want to find the maximum momentum for a given amount of fuel.
The above reduces to
p/m = c sqrt(1 - (m_u/m)^2)

So in other words, you get the most momentum out when you convert all of your fuel to pure energy.

Velomobiles are fast

So I learned about Velomobiles today.

They're pretty cool! Here's a table of roughly how fast you would go compared to on a normal bike:

Description	Power	Speed (velomobile)	Speed (normal bike)
High effort	400W	107 km/h	28 km/h
Cruising (jogging equivalent)	200W	85 km/h	22 km/h
Almost no effort (walking equivalent)	60W	57 km/h	15 km/h

I got these numbers by starting from the Quest velomobile top speed of 107km/h with a high-performance rider and projecting down, and the normal bike speeds from the wikipedia page, projecting up (they match my normal riding patterns pretty well).

You can do your own projections using the following equation (change the initial speed and power ratios as appropriate):

15 km/h * ((400W / 60W)^(1 / 3)) = 28 kilometers per hour

Selecting different colours for categories when drawing graphs

I recently needed a set of colours for color coding a diagram (this one). The wonderful d3.js has several colour schemes but they always top out at twenty colours. After googling around for a while I couldn't find anything good so I wrote a generator instead. Here's what the first version looks like:

You choose two lightnesses and a grid density, and it selects colours one after another and prints them out.

This was OK but I wanted a bit more flexibility in the preselection of colours, so I wrote a second (more complicated) version:

The second version allows you to specify any filtering function on which colours are allowed. So you can, as in the above example, choose from all colours that are a certain distance away from another colour (for consistent contrast).

Both versions operate in "LAB" space (as explained in the About section of the second one) so that the colours are spaced by "perceptual" distance -- the distance between two colours is directly related to how different they look to a (typical) person.

Each time the generator chooses a colour, it chooses the one that is furthest away from all the previously selected colours. This means that the first few colours are very different but as more colours are added they get closer together (because there isn't any other option).

Here are some other examples from the (second) colour generator:
