Well, when having a hard problem, just ask the expert.

I could have said it, but you did it first. Thanks to you, universe knowledge and mankind made a leap. Congratulations and many thanks!

You are right. But could you have wait for RUclips 7D? I could not, so I found this solution to this problem useful.

@@xhellas im the expert here

Great! Sounds exciting. Notify me when it is done please!

@@xhellas sorry I didn't mean disrespect, if you took it that way. I just came back to post comment on the original video. Then I saw your video so thought of commenting here as well. Thinking which one will pay me better😆✌️

@@PrashuRGupta it did not took it badly. I was just sincerely waiting for your proposal 😂

Oups! I gave you the work done for another client... Too much work, too much success, you know what I mean. Don"t you like it anyway? These are 2023 colors and harmony, trust me. And happy new year!

@@xhellas Is it me or we both are frenchies speaking to each other in english ? (the "oups" betrayed you). Non, t'as propal est excellente. Paci e saluta comme on dit chez moi.

Shall we add a blinking effect on the paper edition?

Did you subscribe to my chanel?

We follow your written specifications. We are deeply sorry than they does not reflect what you have in mind.

@@xhellas You're being passive-agressive.

@ it is the one that answers the client, not me! Aren't business relations often of this kind?

I have some answers : A) lines can be curved lines B) is it really possible to draw a line. Is it really possible to draw anything? Yes if you drawing induces a perception, an understanding. What you see here are lines while before drawing there was only a plain background. So I think that we can say that lines have been drawn. C) the pencil used was "blue" while you can see "red" lines on the final drawing. Color are here between double quotes in the previous sentence. Did I really omit the color requirements? Could you be clearer?

@@xhellas In Geometry a line: 1. is straight 2. extends in both directions without end (infinitely).

I wish this wasn't that visible, but well, I expected this to be known one day or another.

Then let sign another contract with modification changes as specifications .

I was told that straight lines and curved lines were both lines...

en.m.wikipedia.org/wiki/Line_(geometry) Vs. en.m.wikipedia.org/wiki/Curve

how on earth would that help?

@@MrMinermation At least my lines would be straight and orthogonal. These lines are bent.

@@dasc0yne theyre clearly not parallel as they meet and only some are perpendicular, which can already be achieved on a flat surface.

oh and they're bent

and not able to be on a road

Adorible? Is this like lovhatable?

Let's enter The Twilight Zone...

@@xhellas: No “Twilight Zone” necessary. WTF does that even have to do with anything? It's just drivel. You just couldn't fulfill the conditions. (Obviously, since they're impossible.) Too bad you can't just admit that (even to yourself?), but persist in spouting gibberish in your “defense”. Next you're going to say “But it was just for fun, can't you appreciate a joke!” Yes I can - *if* they're funny. Which this might have been if it hadn't so obviously violated the given conditions. But it did, so it wasn't.

@@ChristianConrad I believe, I think, I hope, that we agree that only blue ink is used to draw whatever can be seen here, including the cat. What can be seen? Lines, that are red. Oh yes, these lines are curved, not question about this. How many? Let say an integer greater than 6 and lesser than 8, so lets pick 7, using a quite random generator that agrees with these bounds. I did not try a WTF dice, but let me know if you do. Do each line intersects with each other? Yes, and with a straight angle. Now let put what precedes in a single sentence : 7 red lines drawn with blue ink, intersecting each other orthogonally (with a cat). No line pairwise parallelism is advertised here or elsewhere in the video, nor orthogonality. What did you expect?

@@xhellas man, maybe you're right. But... You forgot to inflate the balloon (kitten shaped). Everything else is useless. And you call yourself an "expert"?

Only under Euclidean geometry can you not have parallel and perpendicular lines at the same time. But if you paid attention to the meeting they said pretty explicitly to ignore geometry.

Actually nowhere. They weren't meant to be in the deliverables. Right?

Don't worry, be happy...

According to the Concise Oxford Dictionary of Mathematics (4 ed.) : "(in two dimensions) Usually implies a straight line, though in certain contexts it can mean a curve.". So no it's not always a straight line.

@@thestultavekidjo that "in certain contexts" would be the "unless otherwise specified" part, that leads my "always" statement... So my statement still stands as it was.

They specified otherwise when they said ignore geometry.

​@@giantnoah "[Geometry] is concerned with properties of space that are related with distance, shape, size, and relative position of figures." (wiki quote). As such, if you ignore geometry, you can not draw lines *at all* , because lines *are* geometry...

Well, many people ask to change the title of this video. So let's do it!

Kind of...

No please! Do you want a little present to avoid this?

When they cross they are. Aren't they?

they cross at right angles but perpendicular is a relationship between two straight lines or a straight line and a plane. the lines are not straight, so they are not perpendicular. 7 Red Lines is not a puzzle to be solved, it's an example of how bosses use technical jargon incorrectly because they don't know what it means. Asking for seven red lines, all strictly perpendicular doesn't make sense because being perpendicular is not an inherent property of the line, it's a relationship between the line and something else. Since they don't specify what the lines should be perpendicular to, and on a 2D plane seven lines can't all be perpendicular to each other, the request doesn't make sense.

My video is an example of a maybe surprising realization of what one could think unfeasible. The cat appears lately because if it were there when the lines appears he could be very afraid and had a hearth attack, or more likely lose all its hairs. Additionally, for your knowledge, the wood from which lines are extracted is drawn from a rare species of Canada birch.

MalcolmCooks actually, the definition of a straight line is not that strict. Wikipedia even says that the definition of a line is often an axiom of mathematics (aka, it's kinda arbitrary). For example, you can have three "straight" lines be perpendicular to each other, if you draw them on a sphere.

There was no definition, how many dimensions should be used for this task. So if you draw a hypothetical representation of 7 spatial dimensions, 7 lines can easily be drawn perfectly perpendicular to each other.

The green lines are transparent

no it needs 2 red perpendicular lines drawn with green ink, and 2 red perpendicular lines drawn with transparent ink, but all red and perpendicular to each other

and the balloon

This is true from 0:46. Yes!!!!!!!!!

Izzy Lopez A line doesn't have to be straight.

Yes, it does… en.wikipedia.org/wiki/Line_(geometry)

Alan Larimer kitten. Not cat. Kitten. Alan please, don't confuse the issue any more than necessary! The task is set, after all

Really? But they are orthogonal aren't they?

woops! i meant to say that they're not strictly orthogonal - because i guess they are perpindicular. From what I remember in school, orthogonal means it's not projecting onto the same planes. so these lines wouldn't be orthogonal at all ----- if i remember correctly.

Hush ... it must remain secret!

Then you shouldn't make this video LOL Very smart :)

Maybe these lines are not that straight. But they are not meant to. Is it worth a comment?

A line is a very specific kind of curve, and those are not lines.

@MDucky The non euclidean geometry exist! You can project this on an specific 3D shape and then you will have your complaints resolved.

Since the manager and the clients don't know care about sensible geometry, I think this is they can't tell any different.

A line doesn't have to be straight.

Sad but true...

What if only an eraser was the tool used, and the blue was a nice spring sky appearing progressively?

Alex andre Then you did not use the blue ink to draw red lines which does not comply with customer's request.

A little blue ink was needed to hide some clouds in the sky. But not so much, actually.

eraser = transparent ink?

TR the definition of a line

long thin mark [countable] a long thin mark on a surface a straight/wavy/dotted/diagonal line a vertical/horizontal line parallel lines Draw a thick black line across the page.

In mathematics lines are strictly straight

A line is not a line once it has been bent. And the point of intersection doesn't make two lines perpendicular, having opposite reciprocal slopes does

A line is a line, bent, curved or otherwise. Straight is just one attribute a line may have. From Oxford: Line - "long thin mark" [countable] a long thin mark on a surface -a straight/wavy/dotted/diagonal line -a vertical/horizontal line -parallel lines -Draw a thick black line across the page.

Nice one. You should have zoomed an intersection of these lines because here, we may have a doubt! What about a fractal solution?

In geometry a line: • is straight (no curves), • has no thickness, and • extends in both directions without end (infinitely).

Maybe but who really knows? Actually no human being ever saw a real line since it has no thickness and as a consequence no surface to reflect or absorb light...

+Alex andre you got me there

Then technically you can't draw them :) Brilliant job btw

The transparent green ink is used from the begining to the end of the video. It draws grass and it is needed to keep the cat steady. I should have emphasized that, sorry. Thank you so much to care about this!

Im still missing the baloon
