Ubuntu Boot-Repair

If you have Ubuntu Linux OS installed in your computer and your computer does not boot into Ubuntu, most likely it is a GRUB issue. It can be easily fixed using Boot-Repair. First you need to have a bootable Ubuntu USB stick ready. Here is an instruction on how to make a bootable Ubuntu USB stick. An Ubuntu live DVD works too but I noticed most laptops nowadays don’t come with a DVD driver. The following are the steps you need to take to repair your boot.

1. Boot your computer into Ubuntu from bootable Ubuntu USB stick. If boot from USB is not on top of the boot-order in your bios settings, as soon as computer starts, press F9 for HP and F12 for Dell and Lenovo, for example, to enter bios boot menu.

2. Once your computer is booted from live Ubuntu USB stick, choose “Try Ubuntu” instead of “Install Ubuntu”.

3. Open a terminal and run the following commands (press enter after each line):

sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt update
sudo apt install -y boot-repair && boot-repair

4. Once Boot-Repair is loaded, click on “Recommended repair”. The repair is done, reboot your computer to see if it boots into Ubuntu.

Islands of Space

I stumbled upon a Wikipedia entry that says the idea of warp drive first appeared in the sci-fi novel Islands of Space by John W. Campbell Jr. If I were a rare book collector, I would’ve wanted to buy the first edition (1957). Only 1,417 copies of the book were printed back then. Campbell is also the author of the novella Who goes there? which the movies The Thing from Another World (1951) and The Thing (1982) were based on.

I don’t know how Miguel Alcubiere got the idea about warp drive. Could it have been from the Campbell’s book or, from Star Trek? Regardless, the importance and significance of good science fiction cannot be understated, in my opinion. Good science fiction inspires and influences real science as was the case of Jules Verne and Arthur C. Clark, for example. Unfortunately, good science fiction is hard to come by nowadays. A lot of the stuff coming out today as sci-fi are simply just garbage, absolutely nothing about science. People seem to have become so dumb today that they can’t distinguish real science and fantasy, magic, supernatural stuff.

Harvard top cancer researchers faked data

Four top Harvard cancer researchers are accused of faking data by photoshopping images and test results. The four researchers include the CEO and COO of Harvard affiliated Dana-Farber cancer institute. The investigation in this allegation resulted in the retraction of six papers and the correction of dozen others. More details can be read at

This is the blog site of a British molecular biologist Sholto David who discovered their forgeries. What a shame! These morons are also faculty members of Harvard medical school. Apparently, Harvard is not what it used to be.

It appears that every part of the world is corrupted to the core: governments, politics, banks, businesses, education, science, religion …

New Direction

In most part of my life, math has been the sole purpose of my life. Regrettably and quite belatedly, I have come to the realization that that purpose of mine is not achievable, mainly due to the lack of a talent. An unachievable purpose is like chasing a ghost. After all, I have been chasing a ghost in my whole life. I need a new purpose of life that is achievable for the short remainder of my life. Without a good purpose, life is not worth living.

This year, I am going to wrap up some of my unfinished research projects that can be completed. Afterwards, I will be ceasing my futile and fruitless attempts on fundamental research in math and physics. Instead, I will be concentrating on computational and mathematical modeling in finance and biomedical science (especially cancer research). I want to make money and help save people from cancer (I myself is a cancer survivor, at least for now) using math. I think that’s good enough purpose for me.

Mathematics

Have you ever loved someone who is way way out of your league? No matter how much you love her, she wouldn’t even notice that you exist. Out of frustration and despair, you finally decide to walk away from her and forget her, but to no avail you just can’t. No matter what you do, you can never stop thinking about her and loving her. Luckily for me, she was not the only one I loved. But there are others who loved only her and some of them tragically ended their lives after realizing that they are not good enough for her.
