I decided to calculate the greenhouse gas emission from the energy used to heat the water for the showers I take over the course of a year. In my last post, I calculated the amount of energy used to heat … Continue reading →

\(x^2+x-20=(x-4)(x+5)\) \(10.5(1+r)^{30}\) \((6.71\times10^8)\times(2.3\times10^{-4})\approx1.54\times10^5\) \(\pi L (1- \alpha) R^2 = 4\pi\sigma\ T^4 R^2\) \(56\text {mi} \times \frac{1.61 \text{km}}{1\text{ mi}}\approx90\text {km}\) \(56\text {mi} \times \frac{1.61 \text{km}}{1\text{ mi}}\approx90\text {km}\) \($10,000,000\times(0.98)^{100}\approx90\text{km}\) \(7,681,113,346\approx7,700,000,000=7.7\times10^9\) \(150\text{m}\times\frac{4.5\times10^6\text {kg}}{1\text {sec}}\times\frac{10\text {J}}{1\text {kg}\times \text {m}}= 6.75\text {GW}\)

Hi I’m Katie! I was drawn to Math 33 because math has never been my strong suit, however, I do enjoy science and am more interested in learning more about climate change. I have taken environmental science classes before and … Continue reading →
