I don't know why educational facilities don't bother to make visuals as everyday learning material. they like to encrypt things and hope that we unencrypt them and learn it. its an inefficient learning process given to what technology we have today.
But the process of understanding and internalising the so called “encryptions” is the true beauty of maths and science, the visuals can come later to understand the physical meaning of what you are doing during maths, a great example of this is 3blue1brown, because when you are working with maths and science in industry or in academia, the problems aren’t so available in visual format, you have to understand what the problem is asking and try different techniques to figure out, and you would only be able to use these techniques if you made an attempt to understand and internalise them yourself instead of being handed everything on a platter
Step 4. Make sure you are comfortable with your calculator. I know with mine depending on whether I'm entering degrees, radians, or gradient I can switch between those modes. If I want decimal notation then I set my calculator to approximate and if I don't want decimal notation then I set it to exact. Just make sure that when you enter in the values it conforms to the order of operations.
Im a ninth grader in highschool right now, and i have looked all over the internet. There was never any channel as helpful as domain of science, you helped me so much, i dont really understand alot of it, but i know i'll get there someday. This chanel explains so well. I just want to say thank you!
Few days ago, I finally got it! Math is a foreign language. As a lawyer, I was so proud of myself... Now, after I had decrypted this code, one question was standing : "HOW DO WE READ MATH?". The question seemed so "stupid" to me that it has never crossed my mind that someone, somewhere would take his time to explain and answer to this dumb question🤦🏿♂️! WHAT A VIDEO!?!!!🤩🤩 And, at the end, WHAT A SMART QUESTION!😱😋👌🏿 Thank you for sharing your knowledges👏🏿👏🏿👏🏿 From Paris-France🇨🇵🇨🇵
i wish i had content like this when I was younger. It wouldve helped me a lot to better understand math. the way my teachers taught me or the books just made me more confused which was why math was always my weakest subject growing up.
Yeah. They always teach it as seemingly vuagely and unhelpful as possible. They'll just keep repeating what essentially ammounts to "why can't you do it? It's easy! Let me do it for you to show you that!" Without actually bothering you explain WHY or HOW and we're expected to just immediately understand what's going on with no real explanations.

Great and helpful video! Thank you! For SCD guys, I realized that SUM is just a for loop. i=100 SUM i=0, i^2 is for(sum= 0, i= 0; i!= 100; i++){ sum+= i^2;}.
Oh, how I wish I had this explanation back in the Seventies when I was in Highschool. It would have saved years of anguish. So clear and informative. I can remember the horror of trying to make sense of Letters suddenly appearing in Sums and the pain it caused me. Bloody dreadful teachers back then, probably got off with a power trip of superiority of knowledge over us ordinary kids.
I am astonished with the amount of simplicity there is to seeing these concepts embedded within mathematics. I wish all educators would be able to condense information this easily.
I feel this is the most difficult part about learning mathematics. When someone explains it in words, I have no problem. When I have to stare at these hieroglyphics, im lost within moments.
Thank you so much! This video is so informative! I got my memory back and now I’m in track from 0 in math! But with this video ! I got a lot of encourage to learn it all again! God bless!
I wish I had studied more mathematics at uni. When I first studied calculus it was a revelation to me. As a biologist, we didn't have to do a lot of at undergrad level however, I opted for a calculus course in my first year. I don't think I was a natural mathematician, but my grades were very respectable. I'm sure I could have studied physics or mechanics- don't know why I didn't- mayhap my love of genetics was too strong. Anyway, on the strength of this vid I have subscribed. Looking forward to other presentations. Flaxen Saxon.
I have always disliked math and have been a huge history nerd but like the comment by akjLm53 said, I do feel shut out of a whole world. I want to learn all the complicated things of math and explore the rabbit holes but I don't know how to start.
it's weird how I've come to like maths now unlike when im younger, i realized math is a wonderful human invention, you'd be able to do cool things in just a piece of paper
How I wish I could go back 30 years and regard this as my first primer in maths, which was so badly taught then, it put me off for life. Not a single one of the explanations in this video was explained back then - not a single one! Somehow we were assumed to know half of this from primary school, but most of us did not. Thank you for starting me from scratch with so much more clarity than I ever was offered all those years ago.
That was really helpful for the first four minutes but then I needed you to continue explaining the meaning of each letter/symbol as I practiced trying to decide which were the variables, constants, etc when you came to integrals and derivatives
josh mcgee Is this comment sarcastic, or is something as elementary as being able to read an equation really worthy of 'linking people to this for years to come'? It hardly gets even more basic than that...
before I started university I didn't understand the fundamental principles behind an equation being a relationship between things, or how variables related to the xy plane, etc. A typical high school math class teaches people what to do, not what it means. This video quickly summarises what these very fundamental concepts mean
Missed you! Keep up with the great content man Btw, just entering college to study computer science. I wish to follow the academic path, and you truly inspire me. Thanks!
algebra should be approached with the mindset of it being another language. I think being fluid in the language of math would allow people to not be scared of math and help them learn it better. I and many others were just taught "Solve for x" as the extent of how math works
My favorite thing to do is read math equations that are in the background of shows and movies. I just realized how lame that sounds but I still love it.😁

One of my favorite things about going into math instead of physics was not having to worry about units, other than maybe measuring in degrees sometimes instead of radians.
Also, the index in the summation is not a variable, it's a dummy variable. You could replace i with an emoji, everywhere you see it, and the summation evaluates to be the same
Yes! And I'm going to be working on a monthly schedule from now on. The drawing and animation just takes a long time so I've also been toying with the idea of making more talking head videos, but still with high quality explainer content. Is this something people would like to see?
Its nice to see you uploading again! The drawing and animations can be helpful sometimes but I would also enjoy more "talking head" videos, so in my opinion, do what you think you've got time and energy to do. No visual representations will probably require lengthier explanations some times though.
Domain of Science Most successful science TH-camrs make "talking head" content (SciShow, Vsauce, PBS Spacetime, Veritasium...). Videos like this will definitely be popular ;)
Domain of Science You could talk whilst writing/drawing on a sheet of paper in front of you/camera (or use pre-drawn slides to illustrate a point) - similar to Numberphile videos.

All you have to do is practice. Even if it is hard in the beginning even a few minutes a day until you understand the topic is enough. Just do it more than one time and in different days to remember. Slowly math will look simple.
inverse radius square rule describes a strength which varies with the distance from a fixed point. I find it helpful to know when you see it, you can visualise the problem with spheres...
Strange that you did not talk about how we *CAN* take the square root of a negative number. But the answer lies in the complex realm, and not in the reals. To take the square root of -16. factor out the -1, and then the square root of 16 is 4. The square root of -1 is *_i_* . So the square root would be 4, times *_i_* , which we would write as 4 *_i_* . My TI-89 graphing calculator would have no problem with this, as it does complex numbers as well.

Situation:
You're working in PowerPoint and you've been inserting MathType equations and moving them into position every time. If there is inline text that follows the equation, you must add enough space to allow for the equation. If you add text above the line containing the equation, or if you edit the text, you have to move the equation every time. It would be nice if the equations were truly inline, like in Word, and would flow with the text.
Background:
PowerPoint doesn't allow for inline objects of any type -- drawings, photos, logos, charts, etc. -- and since MathType equations are "objects" that are inserted onto the slide, they cannot be inline either. Therefore, the method described here uses MathType, but the equations produced for PowerPoint are not MathType equations; they're "OMML" equations.
We do offer one workaround in our article MathType Works With PowerPoint, and that's still a viable option. The method below presents a different solution.
Note: Since PowerPoint 2016 for Mac interacts with MathType in a way quite differently from any of the other versions of PowerPoint covered here, we cover that version separately below.
Creating inline equations in PowerPoint for Windows
Since PowerPoint does not allow inline objects, which all MathType equations are, we're going to use MathType to create the equation, but the equation that's actually on the PowerPoint slide will be an OMML equation, as described above.
Open MathType as a separate application -- do not open it by clicking MathType on the MathType tab in PowerPoint. If you're unfamiliar with opening MathType as a separate application, you can get to it through the Windows Start menu.
Create the equation in MathType, then select & copy it ("cut" is actually better than "copy") and paste it onto the slide. Tip: You'll know it's in the right format if you click inside the equation, and you seen the Equation Tools tab on the ribbon:

If you clicked inside the equation, part of it will be shaded. If you didn't click inside, or if none of it is shaded, click inside and it should look something like this:
result of clicking inside the equation
Now "select all". Easiest way to do that is with the shortcut Ctrl+A. Now it looks like this:
result of "select all"
Now copy it -- Ctrl+C. At the point in your slide’s text, insert an equation, either from the Insert tab on the ribbon, or with the shortcut Ctrl+=. It should look something like this:
Now you're ready to paste the equation.
Don’t click inside the gray area, just paste. Now you’ve got an OMML equation there - the one you copied from MathType, and it’s already sized correctly. Also, note above that I had a space after the colon and before the equation. No longer. I must go back and add a space:
After pasting from MathType, you have an inline equation.
Remember, this is an OMML equation, not a MathType one. If you need to edit it, you can click inside and edit it directly if you want. If you'd rather use MathType, you can do that too. Click inside, select all, copy, then paste into MathType. Make your edits, then select & copy it from MathType, then paste in place of the old equation (which should still be selected).
Creating inline equations in PowerPoint 2016 for Mac
Since PowerPoint does not allow inline objects, nor any objects that are not Microsoft Office objects, we're going to use MathType to create the equation, but the equation that's actually on the PowerPoint slide will be an OMML equation, as described above. We'll also be using Word 2016, since it is able to create an OMML equation from MathType, and PowerPoint is not.
Open MathType from the Applications folder.
In MathType's Preferences > Cut and Copy Preferences, choose "MathML 2.0 (namespace attr)" from the MathML or TeX section. Click OK to close the dialog.
Open Word 2016.
Create the equation in MathType, then select & copy it ("cut" is actually better than "copy") and paste it into the Word document. Tip: You'll know it's in the right format if you click inside the equation, and you seen the Equation tab on the ribbon:

Click the blue tab to the left of the equation. If the blue tab isn't showing, click inside the equation, then click the blue tab. This will select the equation:

Copy the equation (again, "cut" is actually better than "copy"). At the point in your slide’s text, insert an equation, from the Insert tab on the ribbon. It should look something like this:
An OMML equatoin inserted inline in PowerPoint 2016 for Mac.
Don't click inside the gray area; just paste the equation you copied from Word. It should look something like this:
OMML equation in PowerPoint 2016 for Mac, pasted from Word 2016 for Mac.
Remember, this is an OMML equation, not a MathType one. If you need to edit it:
You can click inside and edit it directly if you want.
If you'd rather use MathType, you can do that too. Click inside, select all, copy, then paste into Word 2016 (it will not paste directly into MathType).
Before you paste into MathType, confirm Word's settings are correct for this. In Word's Format menu, choose Equation Options (at the bottom). Click to select the option to "Copy MathML to the clipboard as plain text". Click OK. You should only need to do this once, but in the future if equations don't paste properly into MathType, check the setting to make sure it's correct.
Copy it from Word and paste into MathType. Make your edits, then replace the old equation in PowerPoint with the newly-edited one, using the techniques above.
