10 Toys and Games Made with Cardboard Boxes

When the holidays are over, parents are often left with a mound of flattened cardboard shipping boxes and bored kids. The solution? Use those boxes to create fun new toys and games! The possibilities are as endless as your imagination (or your Pinterest feed). Make a fort, an easel, marble mazes, boats and more. With each of these crafts you get an engineering or art activity in the creation of the project, then the fun of playing with the end result.

1. Is it safe to use insta clears on my canon camera lens?

I am against all fluids on lenses - even lens cleaning fluids - use them enough and in a few years you will have molds. Camera lenses are not like glasses lenses, they can trap moistures like cleaning fulids and the end result is molds. Use a micro fibre cloth. Get one from a glasses shop or photographic supplier - camera shops. a

2. As an end result does marijuana effect your vision?

sure! i heard coke is good too! it makes you feel smarter regardless of what the rest of humanity thinks. so dont forget to take ur daily dose of coffee n cigarrettes like Christopher drew and ur coke strip before bed time. do weed ONLY at lunch time!!! very important!!!.

3. SINGERS POLL: Have you ever recorded yourself singing, and did the end result lead to never singing out loud..?

Yeah. I recorded my singing once and I was not too impressed. My voice is sort of deep and loud and shaky and annoying. But that's just my opinion. I used to have a really good voice but I do not sing anymore.

4. With a phased UI change, how do you ensure the end result is uniform?

There are probably many ways to achieve this, but here are some I've used in the past:

5. Why does matchlist() return empty strings at the end of the result?

matchlist() always returns the list of 10 items (the matched string and nine submatches - just like , 1, ..., 9 in :h sub-replace-special). The last five were not used, so they are set to empty strings

6. what is the end result of transcription?

messenger RNA. DO not confuse this with translation as translation is the the making of polypeptide chains from the mRNA at the ribosomes

7. Geometric Algebra Rejection, Projection and reflection rotation, confused on how end result is actually calculated

I have not seen the video but maybe can help you.This implies would need to take the dot product of u and v, a scalar, then take the geometric product of that scalar... I do not understand how I am supposed to do that (it would require taking the dot product of a scalar and taking the wedge product of a scalar and a vector, which makes me think the un-generalized definition is not what I want here?)No, in the case of a scalar and a vector, the geometric product (gp) reduces to the familiar vector space product-with-scalar, so gp($alpha$, $u$) = $alpha u = alpha (ucdot e_1) alpha (ucdot e_2) alpha (ucdot e_3)$. So the projection of $v$ on $u$: $(u cdot v) u^-1$ = $frac1|u|^2(u cdot v) u$, just the same as in vector space.Similarly, Rejection of v onto u is GeometricProduct(GeometricProduct(v u, inv(u))) which if u is unit length, then v u u should be v using the contraction product because v,u ^ u = 0, which also does not make any sense (clearly the rejection in the example shown is not going to be v, the vector being projected itself...)Considering $|u| = 1$, the rejection $(v wedge u) u^-1$ is equal to $(v wedge u) u$. The expansion is $(v wedge u) cdot u (v wedge u) wedge u$, since $(v wedge u) wedge u = 0$ the rejection is $(v wedge u) cdot u = -(v cdot u) wedge u v wedge (u cdot u)$. The term $(v cdot u) wedge u = (v cdot u) u$ since the wedge product of a scalar and a vector reduces to the familiar vector space product, and since $u cdot u = 1$, the rejection is $-(v cdot u) u v$.Finally, while it did make sense why we needed to do two reflections to achieve a rotation, and how this absolutely shows quaternion analogies, I did not understand how the function could actually be calculated with out running into bivector scalar and vector scalar geometric products. These geometric products reduces to the familiar vector space products, they commute and only can change the weight of a k-vector but never its attitude
