Immersion Blenders / Stick Blenders – Breville BSB510XL

Immersion Blenders, also called Stick Blenders, are hand held blenders that you stick into the food you are preparing, rather than the other way around (i.e, a traditional blender).


Immersion blenders started to become popular among the 20-something singles crowd early in this century. This demographic tended to not have the space for or  the interest in having a traditional blender. But these people were really getting into smoothies, and wanted to prepare some for themselves in order to save money. Stick blenders really are the perfect device for making smoothies. Throw your frozen fruit, juice, yogurt, etc., into a large cup, insert the immersion blender in the cup for a few seconds, and you’ve got yourself a smoothie!

Immersion blenders are also good for pureeing soups and a variety of other tasks. They are definitely a good entree into the blender universe. And you don’t need a powerful stick blender power to prepare smoothies and soups– a basic model will do. Alton Brown and Tim Ferriss are among the well-known proponents of the immersion blenders.

Tim Ferriss prefers Breville, specifically the Breville BSB510XL Control Grip Immersion Blender.

This blender is definitely powerful enough for almost any kitchen task. The blade portion is detachable from the handle, and the bowl attachment works well for blending and storing the stick blender up right. The design gives it a power tool kind of feel. This is a very good medium-to-high end purchase for immersion blenders (about $100).

Alton Brown likes to use Kitchen Aid stick blenders on his TV show. These are decent products to start with, and worked well for us. However, we have heard some design complaints, most notably that food tends to get stuck in the cracks and seals in the bowl, and that the blenders are less than durable.

The KitchenAid KHB2351CU 3-speed Immersion Blender is less than $100, and has a variety of different blade and whisk attachments that can go with the handle. It comes with a carrying case for all these parts. We found the large variety of attachments to be a bit confusing, however.

The KitchenAid KHB1231CU 2-speed Immersion Blender is a simpler model without all the attachments, for less than $50.

For a very simple model, one speed with no attachments, we like the Cuisinart CSB-76 SmartStick 200-Watt Immersion Hand Blender, also less than $50.

Bandages Not Included!!

Beware! The blade in the bottom of a stick blender is sharp, and rotates very fast. It can cut you badly. The New York Times has an article on this, titled Bandages Not Included. Would you stick your hand in a lawn mower to remove some grass without unplugging it? The same goes for removing a sprig of mint from an immersion blender, especially since they generally have very sensitive triggers buttons. For those models with detachable blade portions, you can remove this half from the handle top (which has the motor) instead of unplugging it, which is a bit much more convenient. I find this to be a more important convenience feature than the actual interchangeability of blades.

Aeris Velocity Full Foot Scuba Fins

Being a freediving instructor, you might guess that I am somewhat thoughtful about the fins I use for diving and snorkeling. This is certainly true, and for serious freediving, I can tell you a lot about the souped-up, $600 carbon fiber fins with all the bells and whistles. And while these fancy fins do have their place, for general snorkeling and diving, simple is just fine, if you know what to look for.


The most important feature with respect to a fin is the FIT. A cheap fin that fits your foot well is much better than the latest multi-hundred dollar dive techy product if it doesn’t fit well. Imagine running in fancy fitness shoes that don’t fit. You wouldn’t do it, and the same goes for fins. The fit is the interface between your foot and the fin, and this is what matters, because that is how energy is transferred from leg to fin. This energy transfer is also why a simple fin with a foot pocket is better than a buckle on fin (designed to go with dive boots). Remember to account for the appropriate thickness of fin sock when trying a fin for fit.

A word about split-fin technology. I don’t think the feature is worth the price. Split fins seems like an invention for the gear heads, as a way of justifying a $100+ price for an item that should cost you less than $50. It is true when you start kicking with a split-fin, particularly from a stand still, the kick does seem to be more comfortable. This is because the split in the fin is giving way, so that it doesn’t bend your ankle as much. However, this benefit comes at the expense of power. The split-fin can make a session of kicking more comfortable, but because of the split, when you need power, it will be hard to get it. You can check the net for countless stories of people getting caught in currents and being unable to escape because of the lack of power in split fins (which is inherent in their design).

Because of the additional stress/ankle extension that comes from kicking from a stand still, I think it is perfectly fine to have a small amount of split in a fin, to make the initial kicks easier. Another good solution I have seen for this are the small vent holes in the Aeris Velocity Full Foot Scuba Fins. I highly recommend them. They are light, cheap, simple fins, and the small vent holes work well for making it easier to kick. I have done many freedives of more than 100 feet (30m) in them, which I think is a great testimonial. Keep it simple.

Another related tip, which not too many people are aware, of is the use of an item called the Fin Keeper. They are great for snorkeling or diving. Fin keepers are cheap rubber straps that hold the fin onto your foot, kind of like large rubber bands. If you have them on, the fins will stay snug on you feet, and they won’t fall off. This is particularly useful if your fin is a tad too large.

Finally, good Fin Socks are a must for keeping your feet warm and protecting your feet while walking on rocks.

The Underachiever’s Manifesto (2012) – Ray Bennett

The Ten Principles of Underachievement

1) Life’s too short
2) Control is an illusion
3) Expectations lead to misery
4) Great expectations lead to great misery
5) Achievement creates expectations
6) The law of diminishing returns applies everywhere
7) Perfect is the enemy of good
8) The tallest blade of grass is sure to be cut
9) Accomplishment is in the eye of the beholder
10) The 4-per-cent value added principle.

Somehow this book fits into the whole intersectional design philosophy. Especially numbers 6 and 7 from above. This book is a wonderful little monograph from Chronicle Books. Some more:

[A group of students] asked two of the richest men in the world, Bill Gates and Warren Buffet, what they felt was the biggest single factor in their success. Their reply? Being born and living in America. They didn’t have any control over either. It’s a lot like saying that the best way to succeed in life is to choose your parents well. You didn’t choose them, or your genes, or a multitude of other factors that have had an enormous impact on your life. So why put all that pressure on yourself to succeed just because you were given a great mind or superb physical talent? And if you don’t have those things, well…it wasn’t your fault in the first place.

The Black Swan (2007) – Nassim Nicholas Taleb

Economist and hedge fund manager Taleb explains that rare, outlier events are not as rare would like to believe, and have such a disproportionate impact that almost nothing else counts, no matter how large a sample of the non-outlier events we see Therefore we should cultivate positive ones (see discussion of the British Spitfire in Adapt) and guard against the negative ones (the 2008 financial crisis). Rational Wiki does a good job of explaining that a black swan event from the book has three properties:


The black swan is a rare event. It lies outside the realm of common experience and nothing in our past experience points to its possibility. A black swan is that million-to-one chance that statisticians said would never happen because it was a million-to-one chance. Of course, million-to-one chances happen 9 times out of 10.

Extreme impact

When the black swan strikes, it has a massive impact. It is two of the world’s tallest buildings being destroyed, it is a stock market crash that wipes out billions, it is a tsunami or earthquake over a major city. Not only is the qualitative nature of the black swan outside our regular experience (meaning we can’t see it coming), so is its sheer size — a single event can dominate over all other factors.

Retrospective predictability

This property explains the concept of “black swan blindness” or “black swan denial”. It is the illusion that we can actually see things coming. This is because of the narrative fallacy; our ability to construct a sensible story using only the pertinent information, happily discarding the information that wasn’t actually useful in the end. This can only be done with the benefit of hindsight — failing to understand this makes you more vulnerable to their effects.

Rational Wiki goes on the why Gaussian statics betrays us as a model when we rely on it most:

An important point of Taleb’s is his criticism of the usage of “Gaussian” normal distributions as the backbone of statistical modelling when applied to phenomena that do not seem to follow such a distribution and are instead skewed by rare, but massive outliers. He comes up with the concepts of “Mediocristan” — the realm of properties that are Gaussian in nature, like people’s weight or height — and “Extremistan,” where properties like a person’s fortune, market behaviour or success in intellectual or artistic professions are unevenly distributed, and the inclusion or exclusion of one extreme outlier can massively change the overall picture.

This can be best visualised with a quick thought experiment. Take 100, or even 1000 people and compare their heights. Even adding in Robert Wadlow, the tallest man ever recorded, and his massive 2.72 meter frame he would only take up 0.17% of the total height and would barely skew the average by a single percent. However, if you took 100 or 1000 or even 10,000 people, compared their wealth and added Bill Gates’s amassed fortune he could easily dominate the group, holding 99+% of the money in the group. As Taleb notes when discussing this particular thought experiment in The Black Swan, the other thousands in the group barely represent a rounding error in Bill Gates’s personal fortune, or the average daily change due to random economic fluctuation. It’s this particular property that leads Taleb to conclude that history doesn’t just feature black swan events, but is controlled and shaped by them almost exclusively, with the little accumulative changes making little impact in the grand scheme of things. In Extremistan, a single outlier can absolutely dominate the group as a whole.

Adapt: Why Success Always Starts With Failure (2011) – Tim Harford

From the book publisher

In this groundbreaking book, Tim Harford, the Undercover Economist, shows us a new and inspiring approach to solving the most pressing problems in our lives. When faced with complex situations, we have all become accustomed to looking to our leaders to set out a plan of action and blaze a path to success. Harford argues that today’s challenges simply cannot be tackled with ready-made solutions and expert opinion; the world has become far too unpredictable and profoundly complex. Instead, we must adapt.

Deftly weaving together psychology, evolutionary biology, anthropology, physics, and economics, along with the compelling story of hard-won lessons learned in the field, Harford makes a passionate case for the importance of adaptive trial and error in tackling issues such as climate change, poverty, and financial crises—as well as in fostering innovation and creativity in our business and personal lives.

From the book, Chapter 3

The following excerpt from the book discusses the Spitfire, the radical plane that saved Britain during WWII. It is so pithy and evocative I might as well quote it verbatim. A larger section of the book has been excerpted in the online magazine Slate. The business blog by Tim Kastelle and John Steen also has a good review of the book.

When we invest money now in the hope of payoffs later, we think in terms of a return on our investment—a few percent in a savings account, perhaps, or a higher but riskier reward from the stock market. What was the return on [the] investment of 10,000 pounds? Four hundred and thirty thousand people saved from the gas chambers, and denying Adolf Hitler the atomic bomb. The most calculating economist would hesitate to put a price on that.

Return on investment is simply not a useful way of thinking about new ideas and new technologies. It is impossible to estimate a percentage return on blue-sky research, and it is delusional even to try. Most new technologies fail completely. Most original ideas turn out either to be not original after all, or original for the very good reason that they are useless. And when an original idea does work, the returns can be too high to be sensibly measured. The Spitfire is one of countless examples of these unlikely ideas, which range from the sublime (the mathematician and gambler Gerolamo Cardano first explored the idea of “imaginary numbers” in 1545; these apparently useless curiosities later turned out to be essential for developing radio, television, and computing) to the ridiculous (in 1928, Alexander Fleming didn’t keep his laboratory clean and ended up discovering the world’s first antibiotic in a contaminated Petri dish).

We might be tempted to think of such projects as lottery tickets, because they pay off rarely and spectacularly. They’re rather better than that, in fact. Lotteries are a zero-sum game—all they do is redistribute existing resources, whereas research and development can make everyone better off. And unlike lottery tickets, bold innovation projects do not have a known payoff and a fixed probability of victory. Nassim Taleb, author of The Black Swan, calls such projects “positive black swans.”

Whatever we call them, such ventures present us with a headache. They are vital, because the payoff can be so enormous. But they are also frustrating and unpredictable. Usually they do not pay off at all. We cannot ignore them, and yet we cannot seem to manage them effectively either.

The Innovator’s Dilemma (1997) – Clayton Christensen

The classic book on disruptive technology by Harvard Business professor Clayton Christensen. Find out why disruptive technology sneaks up on competitors, and why it is routinely ignored by the dominant market players.

From the Book

There are times at which it is right not to listen to customers, right to invest in developing lower-performance products that promise lower margins, and right to aggressively pursue small, rather than substantial, markets. Generally, disruptive technologies underperform established products in mainstream markets. But they have other features that a few fringe (and generally new) customers value. Products based on disruptive technologies are typically cheaper, simpler, smaller, and, frequently, more convenient to use.

Generally, disruptive technologies underperform established products in mainstream markets. But they have other features that a few fringe (and generally new) customers value. Products based on disruptive technologies are typically cheaper, simpler, smaller, and, frequently, more convenient to use.

Every innovation is difficult. That difficulty is compounded immeasurably, however, when a project is embedded in an organization in which most people are continually questioning why the project is being done at all.

The Medici Effect (2004) by Frans Johansson

From the book publisher

Why do so many world-changing insights come from people with little or no related experience? Charles Darwin was a geologist when he proposed the theory of evolution. And it was an astronomer who finally explained what happened to the dinosaurs. Frans Johansson’s The Medici Effect shows how breakthrough ideas most often occur when we bring concepts from one field into a new, unfamiliar territory, and offers examples how we can turn the ideas we discover into path-breaking innovations.

From the book, Chapter 8

Linus Pauling, Nobel Laureate in both chemistry and peace, once said, “The best way to get a good idea is to have a lot of ideas.”

How then, can you seize the myriad opportunities at the Intersection?

There are at least three ways to proceed:

  • Strike a balance between depth and breadth
  • Actively generate many ideas
  • Allow time for evaluation

One way to handle the need for broad but deep knowledge is to team up with someone who has a different knowledge base from yours.

[Within an individual] one should gain knowledge in one specific area before striking out to other fields. I am not talking about world-leading expertise here, but enough to call it a core competence. Mijail Serruya at Brown’s Brain Science Program says that no matter how broadly other view him, he can “at least teach a second year course in neurology.”

Design and Innovation – Stanford dschool and Book List


dschool logo


One of the privileges I (Robert) have as a research fellow at Stanford is that I get take Stanford classes, including at the Hasso Platner Institute of Design (shorthand dschool). The Stanford dschool focuses on human-centered design and celebrates interdisciplinary thinking. Hasso Platner is one of the world’s great technology entrepreneurs, the founder of pioneering enterprise software company SAP. In most settings, including business and R&D, risk is something to be mitigated and ROI is something to be managed through the use of rational planning. Management, for example, is selected on the basis of experience, track record and deep expertise. Yet the most fundamental innovations tend to come from outsiders or complete novices. Steve Jobs and Bill Gates, for example, had essentially no work experience when they founded Apple and Microsoft.

Cultivation of positive black swans, as Nassim Nicholas Taleb calls them, with their incalculably large returns, requires a different sense of risk, or perhaps risk agnosticism. There are times when expertise is of value (most of the time). But there are times when expertise has no value, and times when expertise has anti-value, because the environment is so new, the rules so foreign, that expertise actually works against you. The expert strives for incremental innovation, the novice can leap frog him by coming up with something entirely new. And while experts are right most of the time, the rare times that they are wrong, they are very wrong, and those few times count for a lot.

The outside/beginner point of view is also useful when you are trying to escape the pull of a local maximum to find a more global one. Expertise is what pushed you up to the hill to the local maximum. Part of design thinking is taking a random walk away from the local maximum, which can be uncomfortable. Eschew local maxima!


Consider the following quotes:

A change in perspective is worth 80 IQ points.
– Alan Kay, Inventor of the Graphical User Interface

I succeeded as a cartoonist with negligible art talent, some basic writing skills, an ordinary sense of humor and a bit of experience in the business world. The “Dilbert” comic is a combination of all four skills. The world has plenty of better artists, smarter writers, funnier humorists and more experienced business people. The rare part is that each of those modest skills is collected in one person. That’s how value is created.
– Scott Adams

In the beginner’s mind there are many possibilities, in the expert’s mind there are few.
– Shunryu Suzuki, First Master of the San Francisco Zen Center

And so, in this vein, I present to you my easy to digest, mostly modern, reading list of innovation that comes from novice, outsider, or intersectional thinking.
