From Einstein's Universe to the Multiverse

Today, we know that the Universe is filled with galaxies, and our Galaxy, The Milky Way, is only one of many hundreds of billions. In turn, each galaxy is made up of billions to hundreds of billions of stars.

Life Lessons from Astronomy

However way you twist it, the blunt truth is that our study of the heavens does not directly impact everyday life on Earth (astrology notwithstanding). Our discoveries do not feed hungry people, cure sick people, or better the lives of poor people. Yet, our ever-expanding understanding of the heavens has profoundly shaped– and will continue to profoundly shape– how the human race thinks of itself and its place in the cosmos.

The Science Behind Why Filipinos Suck at Science

When you hear the word “science,” you might think of that subject in school with the complicated equations on a blackboard that only a super genius can solve, or an image of Einstein, pensive and wise, or Newton’s falling apple. These are all fine associations, but they miss a crucial aspect of what science is—the human aspect, the scientist herself.

[Pinoy Mind Map] Kakanin

Suddenly, strangely, I found myself craving for suman. It was strange to me, this sensation, acute and lingering. I’ve never had one like it before, despite 8 years of living abroad. So I paid attention. And of course, I shared it on Facebook. A friend replied, “Your tastebuds must be getting homesick, Reina.” Indeed, they were. In fact, I was homesick down to my bones.

Just as well, for eating suman is not just about taste. It is a ritual in its own right.

[Pinoy Mind Map] Merienda math

Equations imply balance — whatever is on the left side is the same as what is on the right. No more, no less. Things add up. Even as a kid, I knew that life is rarely, if ever, that neat.

Most times, that can be frustrating. But I’m also beginning to appreciate that that’s a good thing. In fact, the things that make life most interesting — and fulfilling — are those for which 1 + 1 does not merely add up to 2.

[Pinoy Mind Map] Manila

For a long time, I didn’t miss Manila — and now I know why. To miss her, you must first have had her — long enough to lose her. I left much too early for that. The truth is, I did not lose Manila, it was she who lost me.

When I came back two years ago, she took me back with open arms, and hasn’t let go since. And now I long for her, so profoundly, the words escape me.

Meanwhile, there is this song that keeps playing in my head…

[Pinoy Mind Map] Is the Philippines a small country?

We all know that the USA is a big country. In fact, it is the fourth largest country in the world (next only to Russia, Canada, and China in land area). You can probably picture a map of the USA in your head. Do you have it?

Now, picture a map of the Philippines and mentally place it on top of the USA map. How much smaller is it? In your mind, how many Philippine archipelagos can fit inside the USA? We don’t need an exact number, but give it your best guess.

[Pinoy Mind Map] Highs and lows

How high can you go? The peak of Mt Apo, the highest mountain in the country, towers at 2,954 meters (almost 3 km) above sea level, and overlooks Davao City to the northeast, Digos City to the southeast, and Kidapawan City to the west.

…Imagine taking a gigantic knife and cutting the mountain in half, slicing all the way through the island of Mindanao and its surrounding bodies of water. What would you get?

Coming Home

I identify as a child of the Orient, but actually became an adult in the West. Although I’m not one myself, I can relate to Third Culture Kids (TCKs), who were raised in a culture outside their parents’. Many of them spent their childhood moving from place to place. For them, “home” is not a straightforward concept; for me, it is becoming an increasingly nebulous one.

The value of asking questions

When I was a kid, I asked a lot of questions. Isa akong makulit na bata. Thankfully, my Mom never got tired of them. She didn’t shush me, or dismiss me, like other parents would. And even if she didn’t know the answer, she would simply say, “Anak, hindi ko alam (I don’t know), but we can find out together. And we would look it up in our books. Wala pang Internet noon – can you imagine? (We didn’t have internet before. Can you imagine?)”

So I learned early on that it is OK to ask questions. In fact, it was good to ask them- and to look for the answers. And I’ve never stopped asking since.

Reina also maintains the Tumblr blog Pinoy Scientists, where she profiles Filipino scientists from various disciplines based in the country and abroad.

By showcasing their work and personalities, she wants to dispel myths about scientists and encourage young Filipinos to believe that they, too, can become scientists themselves.
