How to solve hard problems

People are asking "How can I solve the homework? It is too hard". Here are some steps that may help you.

Homework 7

Keep your mind sharp. Prepare for the next stage of online learning. Learn how to find biological meaning in genomic data —codon usage, GC-skew— using basic programming tools.

Application: Evaluating Statistical Uncertainty

Practice evaluating statistical uncertainty

Estimating Statistical Uncertainty

Every time we measure, we get a different number. How can we extract meaningful information from noisy data? How much information can we extract? Classical statistics gives an answer to these questions.

Hard problems

Some students argue that the exercise "find the largest value" is too hard. This raises the question "What do we mean by hard problem"? The answer teach us important things about life, the universe, and everything.

Comments on Homework 5

Several students have delivered their homework. Some are good, some are worth looking at them. I want to share them with everybody, so everybody can learn.

Three weeks of no-holiday

Universities in Turkey are closed for at least three weeks, as a way to contain the spread of Covid-19. It is easy to fall into the trap of doing "nothing", watching TV, and read social media. But easy is not wise. Use your time wisely.

Methodology of Scientific Research

What is the value of Science? In this course we will discuss why do we need Science, how Science improves people’s lives and how to do it better.

Computing in Molecular Biology 2

This course is an introduction to Computational Thinking. We will use the tools we learned in the previous course and apply them to model and simulate scientific experiments as a way to understand them.

Should I learn Turkish? What is best for the University?

Some people ask me why I do not learn Turkish. It is a good question. For sure, it will be good for me. I would be able to speak about football with the butcher, discuss politics with my father-in-law, and read my collection of Matematik Dünyası magazine. But, what is best for our University?

My academic ancestors

A database of all mathematicians and their advisors shows my academic ancestors since Persia in 1200. Some famous names among my ancestors.

The Biologist Toolbox: Simulating Systems on the computer

Once we have a description of a system, and a nice drawing to represent it, we can answer some interesting questions. The first question is usually what will happen? In other words, we usually want to know what is the behavior of the system?.

The Biologist Toolbox: Drawing Systems

Can we represent a complex system in a simple and easy to understand way that is still realistic enough to be useful? The graphical representation that we discuss here, based Petri nets, can be used to summarize a dynamical system and can easily translated into a simulation.

Free fall experiment

For the “Computing in Molecular Biology” course I try to use realistic data. It is difficult to do biological experiments in classes, since they require a lot of time. That’s why I prefer to do physics experiments. Last week I did one of those experiments, to generate data that the students will analyze later.

Keep your mind sharp on August

Why do rich kids learn more than poor kids? According to some research, the "achievement gap" between kids of high-income and low-income families is not that rich kids learn more, but that they forget less in the summer holiday. Following this idea, I propose a couple of challenges to keep your mind active during the holidays, and maybe win a nice book.

My Professor got an International Prize

One of my professors got an international award. He had already won the most prestigious national recognitions in Science. Now he became global. This gives me the opportunity to start a series of posts about my world-class professors and their international achievements.
