US Census forms -- Do I have to do it?

Do you have to fill out the Census form?
United States citizens over 18 years old are required by law to fill out the Census form (see the end of this posting for specifics). This form is not available online. It must be completed by mail.

About Me -- Lifestyle




Play - I love basketball, hiking, jogging, swimming and watching funny moves.

Eat - Meat lover until I learned the truth on YouTube through documentary videos such as Earthlings. Became a vegetarian and a strict vegan. It didn't work out. More explanation here.  I try to buy and support organic food and products when it makes sense.


Sleep - 8 hours a day unless a project deadline, presentation the next morning or homework due.

Live - I live in an apartment in the Bay Area, in the heart of Silicon Valley. I climb up and down the stairs from my 9th floor home at least twice a day. It's good exercise and saves on elevator energy. Best of all, I don't have to pay to do it. For transportation, I walk, ride a bike, or take the bus whenever possible. If necessary, I use ZipCar. I used to own a car, and I guarantee you the parking, insurance, registration and maintenance is a pain in the behoozies. My life got so much simpler now that I don't have one. :D

Love - Family, nature, people, animals. I love you all. I have been dating a wonderful Ms. Turtle for several years now. She has been a great source of support and nurture for me. And no, she doesn't look like this. Hahaha, the picture is funny.

Learn - I am currently an electrical engineering graduate student pursuing photovoltaics research. I also enjoy studying history and languages other than English. Travelling has also been a great way for me to learn about other cultures and ideas, especially when I avoid the conventional "touristy stuff".

About Me -- Career




Advancing sustainable energy technology and sharing knowledge to benefit society are my two main career goals. For this reason, I am pursuing a PhD in Electrical Engineering to investigate low-cost solar cell design and fabrication.
