New Method for solving Quadratic Equations

I received this article in the Mensa Brainwave newsletter this morning. Having watched many tutoring students struggle with solving Quadratic equations, I am fascinated by the methodology described here. It makes perfect sense, and eliminates the trial and error method used for centuries.

I am without pencil and paper at the moment, but can hardly wait to pull some out and my math books and try the method for myself. In physics, I have run across some whopper Quadratic equations which, even when run through the quadratic formula, are still quite messy. This look like a vastly more elegant approach.

As always, thanks for reading. I can help your student master Quadratic equations by contacting me at sandy@stellar-student.com

Math and a Snuggle Sack

My BFF modeling the Oklahoma Sooners Snuggle Sack I made her.

When people think of sewing, I’m pretty sure they don’t think of math. They think of pretty fabric, patterns, quilting, and making cool custom garments. Sewing, though, is a lot of math.

Although patterns state the yardage required for a given size and width of fabric, oftentimes adjustments must be made. If the fabric has a nap or one-way design, extra fabric will be required.

In my case, I have been making Snuggle Sacks for special friends and family for a few years. Tonight, I started making another one. One of the components required is insulation. I usually use Thinsulate. I had some leftover Thinsulate from a project I’d completed over the summer. Since the insulation is sandwiched between the inner and outer Snuggle Sack layers, it will never be seen. This was an opportunity to use up my Thinsulate scraps. First, I had to see how much I needed.

To do this, I calculated the area of the completed Snuggle Sack. I then measured the length and width of each of my scraps of Thinsulate. I then calculated the area of each scrap of Thinsulate. Then, I started subtracting the areas of the Thinsulate scraps from the total area needed, to see if I had enough. It turns out I have plenty of Thinsulate, with a bit leftover. But, if I hadn’t applied my math skills to the problem, I might have just bought more Thinsulate, and spent more money and had more fabric laying around the house.

And that’s just one simple example of using math in a sewing project and how STEM Education is used in everyday life.

Thanks for joining me. I hope to see you soon.

You Might be a Professional Tutor if …

I moved to this home six months ago. I had had many of my possessions in storage for over 11 years (LONG story). Although I had most of my tutoring books with me where I’d lived before here, I didn’t realize how many books I had until I unpacked them.

When I’d toured this house, I was thrilled to see the built in bookshelves next to the fireplace. I was so happy that I wouldn’t need to buy or assemble bookshelves. I was certain that the approximately 15 linear feet of bookshelf space would be more than sufficient for my collection of physics, math, chemistry, space, astronomy, database and software books. Boy, was I wrong!!!!

Here are the books I have not yet unpacked, as I don’t have room to store them.

And yet still more of Sandy Eulitt’s Physics, Math, and Engineering Tutoring textbooks

The question now is, what do I do with all these books I have not yet unpacked? I had to buy a tall bookshelf to store my “recreational reading” books, and I am out of floor space for another bookshelf. What to do, what to do. Bonus round, a dear friend of mine and former physics and astronomy professor offered me her textbook collection recently. Ugh. Is there a 12 Step program for withdrawing from textbook collecting? If not, I might have to start one.

Thanks for reading and have a happy day!!!!!

Free Tutoring, Time Management, Study Skills

Math, Physics, and Chemistry Tutoring Background

Tonight I want to talk about study techniques and ideas, things I’ve observed from years of tutoring, etc. First, me preface this by saying I don’t have children, but over the past several years I have tutored countless children, students of all ages. Honestly, the youngest that I have tutored is probably about 11 or 12 and the oldest was into his 40’s. I have tutored a wide and diverse range of subjects from sixth grade math to the calculus-based physics for science and engineering students. The latter class is definitely consider the hardest topic I tutor.

Subjects Tutored

I’ve tutored AP Chemistry, college chemistry, introductory chemistry, a couple different programming languages, AP Calculus, pre-calculus, algebra, intermediate algebra, geometry, Linear Algebra, astronomy, differential equations, conceptual physics, high school physics, AP Physics, AP Statistics, and multivariable, or vector, calculus. There seems to be a common thread that runs through all of this, which constantly amazes me, frankly, kind of amuses me at the same time.

Most parents enlist the assistance of a private tutor as a last resort to help their child out. Maybe it is after the first test comes back with less-than-stellar-grades, or maybe it is closer to finals. The teacher may not be as available as the student needs or is unable to explain the material in a way that the student understands. As much as a student might want, the teacher cannot sit next to the student all night long while doing homework, to answer questions when needed. One thing that I consistently see in my tutoring is that the books look brand new. The books look like they have never been opened. They have no highlighting in them, they have no pencil markings in them, they just have that look of being fresh off the shelf, fresh from the bookstore and having never been used before. And this is something that really bothers me. Remember I tutor physics, math, and chemistry, predominantly. These are, by and large, subjects that have a lot of math. Consequently, the books tend to have a fair number of example problems in them. And I tell students that example problems are “free tutoring”. Many of the students that I tutor when I tell them this look at me like I have just shared with them some great epiphany. I’m very surprised by this.

I don’t understand why students, first, do not read the book and second, do not do the example problems provided within the book. In fact, my experience has been that many of the homework problems use material or techniques that were demonstrated within the example problems. So, if you are a parent and you are struggling with your child’s grades, or you’re a college student struggling with your own grades, the first thing that I say to you is, “Have you read the book? Have you actually sat down and read the book?” Let’s talk about that a little bit more, as I think one of the things that has to be addressed is the issue of time management. We all have busy lives, that goes without saying. College students are juggling three or four classes, often a part-time job, extracurricular activities, clubs that they are officers in, and may be involved in a job search, and we all want a social life, and sleep is always nice. High school students seem to be, primarily, juggling a number of classes, as well as extracurricular activities, and many students are involved in sports; many high schools seem to now be requiring participation in a sport for graduation. So the issue of time management and time budgeting becomes critical.

I’ve tutored high school chemistry, college chemistry, introductory chemistry, a couple different programming languages, calculus, pre-calculus, algebra, intermediate algebra, geometry, Linear Algebra, astronomy, the list really continue. A lot of what I have tutored, and has been most of my tutoring, has been high school students, and most of that has been conceptual physics. A lot of it has also been algebra, intermediate algebra, geometry, AP physics, and introductory and AP chemistry. And there seems to be a common thread that runs through all of this, which constantly amazes me, frankly, kind of amuses me at the same time.

Textbook Condition

Many parents, I think, enlist the assistance of a private tutor kind of as a last resort to help their child out. The student obviously is not getting this material on his or her own, and he or she may have gone to the teacher and asked for assistance, the teacher either may not be as available as the student needs or is unable to explain the material in a way that the student understands; there can be a variety of reasons why a private tutor is finally enlisted to assist the student. One thing that I consistently see in my tutoring is that the books look brand new. The books look like they have never been opened. They have no highlighting in them, they have no pencil markings in them, they just have that look of being fresh off the shelf, fresh from the bookstore and having never been used before. And this is something that really bothers me. Remember I tutor physics, math, and chemistry, predominantly. These are, by and large, subjects that have a lot of math. Consequently, the books tend to have a fair number of example problems in them. And I tell students that example problems are “free tutoring”. Many of the students that I tutor when I tell them this look at me like I have just shared with them some great epiphany. I’m very surprised by this. They already paid for the textbook! Why does it look brand new whenever I ask the student about it!!????

I don’t understand why students, first, do not read the book and second, do not do the example problems provided within the book. In fact, my experience has been that many of the homework problems use material or techniques that were demonstrated within the example problems. So, if you are a parent and you are struggling with your child’s grades, or you’re a college student struggling with your own grades, the first thing that I say to you is, “Have you read the book? Have you actually sat down and read the book?” Let’s talk about that a little bit more, as I think one of the things that has to be addressed is the issue of time management.

That concludes this blog on time management, study habits, tips and techniques to acquire the grade you want and the grade deserve have a good week.

How Math Proofs Really Work

Math Proofs Really are Like This

Having written more mathematical proofs than I’d like, I can assure you that math proofs operate EXACTLY like this. Not my idea of a fun way to spend my time. I sincerely hope I have written my last mathematical proof.
