Name: Titanium Oxide Transitional/Chalcogens Titanium Dioxide is a naturally-occurring compound of Titanium. The chemical symbol for it is TiO2. It was discovered in 1967 by Akira Fujishima. It can be used in outdoor building supplies to reduce airborne pollutants. It’s white, powdery quality can be harnessed for beauty products such as nail polish and foundation. Some […]

Titanium (Ti)
Titanium has an atomic number of 22. It was first discovered in 1791 by Revered William Gregor. It is a transitional metal in period 4. Some titanium makes propellers for boats, airplane parts, spacecraft, artificial joints, and pins for setting bones. Unfortunately, due to its high cost, titanium cannot be used for a wider variety […]
Reducing integers vs. reducing exponents
When reducing integers in a radical, you must reduce based on the index, which could be squaring or cubing the number. For example: ³√27x³ (Cube root of 27 x cubed) To pull the 27 out from under the cube root sign, you would cube the number 27 and put a 3 in front of the […]
Irrational Number: i
For this research assignment, I decided to look into the symbol i. i is defined the square root of -1. It is an imaginary number, and an irrational number, given that negatives don’t have square roots, nor does the number one. This symbol appears in mathematical equations, including the constant ‘Euler’s Identity’ which is e^iπ+1=0. […]
Bubble Gum Lab-Conclusion
The results from this experiment concluded that the gum B was more stretchy and could blow bigger bubbles, thusly proving both hypotheses correct. In part one, we hypothesized that the squishier gum would blow a larger bubble. Gum B was was squishier than Gum A, although this may be because Gum B was in one […]
Mathematical Autobiography
My Mathematical Autobiography: Ever since I was in grade two, I’ve harboured a love for math. I worked tirelessly to learn subtraction which turned to long hours with statistics and trigonometry. Math has never come easy to me-it takes me a long time to figure out each concept and understand it completely. In the past, […]
