"Tuning frictional behavior on the fly has been a long-standing engineering dream," said co-author Katia Bertoldi of Harvard University. "This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.” In addition, the dynamics revealed by these results are similar to those of tectonic faults and thus give scientists a new model for the mechanics of earthquakes, according to their new paper published in the journal Nature.

The best advice I can give to a person starting a business is to stay focused, don’t be discouraged by naysayers and don’t get overwhelmed by the process — you’re bigger than it and you can handle more than you think. Focus on small daily tasks, tackle them consistently, and over time, you’ll realize you’ve built something far bigger than you ever imagined. And that feeling is incredible.
