>There is good evidence that existing genetic variants in the human population (i.e., alleles affecting intelligence that are found today in the collective world population, but not necessarily in a single person) can be combined to produce a phenotype which is far beyond anything yet seen in human history.

>Then the population SD for the trait corresponds to an excess of roughly N1/2 positive alleles (for simplicity we suppress dependence on minor allele frequency). A genius like von Neumann might be +6 SD, so would have roughly 6N1/2 more positive alleles than the average person (e.g., ∼ 600 extra positive alleles if N = 10k). But there are roughly +N1/2 SDs in phenotype (∼ 100 SDs in the case N ∼ 10k) to be had by an individual who has essentially all of the N positive alleles! As long as N1/2 6, there is ample extant variation for selection to act on to produce a type superior to any that has existed before. The probability of producing a "maximal type" through random breeding is exponentially small in N, and the historical human population is insufficient to have made this likely.

the fact that once embryo editing starts every single human that lives and has ever lived is going to get outcompeted by many orders of magnitude

Currently studying past IMAT questions, and this question has me stumped.

Last month Karl walked from Starton to Endham, raising money for charity. His target,
successfully achieved, was to complete the walk in ten days.
He started later than intended and had only completed 12 km by the end of the first day.
However, he walked 45 km on each of the second, third and fourth days, and after the fifth day
he was exactly half way. Poor weather on the sixth day restricted his progress, but 41 km on
both the seventh and eighth days meant that he had completed exactly three
quarters of the walk with two days left. On the ninth day he covered threefifths of the remaining distance,
completing the last 36 km on the tenth day.
How far did Karl walk from Starton to Endham?

360 km
240 km
328 km
384 km
294 km

The answer is 360km, but I have no fucking Idea why?
If W is the whole Way
We can say
12+45*3+x=0,5 W
12+45*3+x+y+41*2=0,75 W
12+45*3+x+y+41*2+(3/5W)+36 = W

You have only a few minutes so solve this, so there must be something obvious I'm missing?

Yes i know this shit is horrible.

I ... guest. The teacher just wrote that and told us to demostrate it. But looking at the post from above it makes me think that he is just mocking us ?

Teachers usually do shit like that to newcomers i guest

Sage the thread if you want this shit made me feel stupid as a log

What's the difference between Euclidean Geometry and Vectors and Non-Euclidean Geometry and Vectors?
