Logicomix is a comic book about British philosopher Russel Bertrand’s life and his quest to form the foundations of mathematics.

It covers heavy subjects such as boolean logic, set theory, Russel’s paradox and incompleteness theorem in a light format: a comic book. It reminded me how powerful and entertaining visual story telling is and how books, comics, movies and photography are all different forms of story telling.

The book takes place during the Second World War and covers Russel Bertrand’s personal life, his upbringing, his academic work such as Principia Mathematica and Russell’s paradox.

The narrative of Logicomix is interesting as well: it mixes the authors trying to write this comic book with Bertrand telling his life story during a talk to convince people whether they should support the war between Germany and Great Britain or not.

Even though it falls short of providing a deep explanation of mathematical concepts presented at times, it is a very entertaining read regardless.

Steve Jobs

This video is full of gems:

I’ve never found anyone who said no or hung up the phone when I called.
I just asked.
You gotta act. Most people never pickup the phone and call, most people never ask.
That’s what separates the people who do things from the ones that dream about them.
You gotta act.
You gotta be willing to fail, crash and burn. If you’re afraid of failing, you won’t get very far…

When you grow up, you tend to get told that the world is the way it is and your life is just to live your life inside the world, try not to bash into the walls too much, try to have a nice family life, have fun, save a little money.

That’s a very limited life, life can be much broader once you discover one simple fact: Everything around you that you call life was made up by people that were no smarter than you. You can change it, you can influence it.

Zero to One


Zero to One is a recollection of notes from Peter Thiel’s lectures on startups and entrepreneurship at Stanford University. Peter Thiel is on the board of directors of Facebook and his thoughts influence Facebook executives and the tech industry.

The book starts with Peter Thiel’s favorite interview question: “What important truth do very few people agree with you on?”. The business version of this question is: “What valuable company is nobody building?”

There are few unconventional ideas in the book that are worth mentioning:

Competition vs Monopolies:

  • Competition is for losers — under prefect competition, no company makes an economic profit in the long run. Whereas a competitive firm must sell at the market price, a monopoly owns its market, so it can set its own prices.
  • If you want to create and and capture lasting value, don’t build an undifferentiated commodity business.
  • Winning is better than losing, but everybody loses when the war isn’t one worth fighting for. Service businesses especially are difficult to make monopolies.
  • Proprietary technology must be at least 10 times better than its closest substitute in some important dimension to lead a real monopolistic advantage. The clearest way to make a 10x improvement is to invent something completely new. Or you can radically improve an existing solution.

Last Mover Advantage:

  • It’s much better to be the last mover – that is to make the last great development in a specific market and enjoy years or even decades of monopoly profits.
  • Business is like chess, you must study the endgame before everything else.

Venture Capital:

  • Venture returns don’t follow a normal distribution overall. Rather, they follow a power law: a small handful of companies radically outperform all others.
  • The biggest secret in venture capital is that the best investment in a successful fund equals or outperforms the entire rest of the fund combined.
  • Only invest in companies that have the potential to return the value of the entire fund. Every single company in a good venture portfolio must have the potential to succeed at vast scale.
  • Andreessen Horowitz has a $1.5 billion fund: if they only wrote $250,000 checks, they would need to find 19 Instagrams just to break even.


  • The value of a business today is the sum of all the money it will make in the future. Most of tech company’s value will come at least 10 to 15 years in the future. Rapid short-term growth at both Zynga and Groupon distracted investors from long-term challenges. But they ended up with the same problem every Hollywood studio faces: how can you reliably produce a constant stream of popular entertainment for a fickle audience?
  • Paradoxically, network effects businesses must start with especially small markets. Facebook started with just Harvard students. The perfect target market for a startup is a small group of particular people concentrated together and served by few or no competitors. A large market will either lack a good starting point or it will be open to competition. Once you create and dominate a niche market, then you should gradually expand into related and slightly broader markets.
  • The greatest thing Jobs designed was his business. Apple imagined and executed definite multi-year plans to create new products and distribute them effectively. Forget “minimum viable products” — ever since he started Apple in 1976, Jobs saw that you can change world through careful planning, not by listening to focus group feedback or copying others’ successes.
  • Recruiting is a core competency for any company. It should never be outsourced.
  • Like acting, sales works best when hidden. People who sell advertising are called “account executives”. People who sell customers work in “business development.” People who sell companies are “investment baners.” And people who sell themselves are called “politicians.” There’s a reason for these redescriptions: none of us wants to be reminded when we’re being sold.


  • Bright college graduates head to Wall Street precisely because they have no real plan for their careers. Once they arrive at Goldman, they find that even inside finance, everything is indefinite. The fundamental tenet is that the market is random; you can’t know anything specific or substantive; diversification becomes supremely important.
  • Since time is your most valuable asset, it’s odd to spend it working with people who don’t envision any long-term future together.

Overall, it’s a quick read with interesting ideas.  I enjoyed his analysis of clean technology market as a case study, and the seven questions that every business must answer:

  1. Engineering:  Can you create breakthrough technology instead of incremental improvements?
  2. Timing: Is now the right time to start your particular business?
  3. Monopoly: Are you starting with a big share of a small market?
  4. People: Do you have the right team?
  5. Distribution: Do you have a way to not just create but deliver your product?
  6. Durability: Will your market position be defensible 10 and 20 years into the future?
  7. Secret: Have you identified a unique opportunity that others don’t see?

His talk at Stanford also summarizes most of the ideas in this book. If you prefer videos over books, you can watch Peter Thiel’s 1 hour long lecture at Stanford’s “How to Start a Startup” course:
