The first flight of the Martin Marietta X-24B lifting body rocket plane on 1973 August 1st was after the first flights of the Northrop M2-F3 lifting body rocket plane and the Apollo command and service module and was the last of the five US heavyweight lifting body designs flown between 1966 and 1975 to study vehicle designed for reentry from space. The Martin Marietta X-24B was a rebuild of the Martin Marietta X-24A.

Lifting bodies attempt to minimize drag by having a fuselage with little or no wing. This contrast flying wings which have a wing with little or no fuselage.

Distance between n-Dimensional Points

(The images and equations only work on my blog)

The distance between two points on the Euclidean plane is just given by a manipulation of the Pythagorean theorem (where Δp is the distance):

$$\sqrt{(\Delta x)^2+(\Delta y)^2}=\Delta p$$

The Δx and Δy in the equation are the distances of the x-values and y-values between the two points respectively (in other words the absolute value of the differences).

This distance formula is easily generalized to the 3rd dimension by adding the square of the distance between the z values into the square root:

$$\sqrt{(\Delta x)^2+(\Delta y)^2+(\Delta z)^2}=\Delta p$$

This generalization of the 2D case can be applied pretty much the same for all nD distances by adding the squares of the distances of each axis coordinate (the ith axis is denoted as x sub i):

$$\sqrt { \sum_{i=1}^n (\Delta x_i )^2 } = \Delta p$$

so i was trying to answer this ask from @gongedtornado, but every time i tried the "post now" button would just straight up disappear. so i'll be doing it this way instead.

protein guy analysis:

i think it's probably because this is a much longer sequence, but this one kind of looks like a globular protein! it's mostly alpha helical, and all the residues are packed in pretty tightly. the confidence scores are still really low, so its probably just the AI having more to work with as it tries to match up this jumble of letters with sequences and structures that actually make sense. still, it looks like something, which is always a little surprising!
