Maybe it’s more of a hypothesis. I’ve been going on about this for a couple of weeks, but I’m not sure I’ve been able to make several of my points clear, so I’ll give it a shot here. Before diving in, note that I have changed the way I plot Continue Reading
Seam-Shifted Wakes

The theory of Seam-Controlled Wakes Post #17
A different idea on the “Laminar Express” Post #16
Nearly everyday, I hear someone say they are “humbled” due to some recognition, award, promotion, etc. It sounds like BS, and I think it’s because it is BS. If you want to feel humbled, put a theory out there on how something works, but continue to ask questions and entertain Continue Reading
A Complete Description of the Laminar Express Post #15
NOTE: The conclusions drawn in this post are based on an erroneous idea about the orientation of this pitch (Figure 4). For the correct ball orientation, this description does not make sense. For a better explanation, see the new post Let me say something important first. This is a fascinating pitch. Understanding it is going to require Continue Reading
What we still don’t know about Laminar Express Post #14
It was exciting to see the flow around a ball in flight experiencing this effect. We spent one day on it and were lucky to get the result we did. The day answered one basic question: is a laminar express different from a standard 2-seamer due to a somewhat forward-facing Continue Reading
Driveline Laminar Express Study Post #13
On January 15, 2019, Eric Jagers, Kyle Boddy, Joe Marsh and Dean Jackson of Driveline visited the USU Experimental Fluid Dynamics Laboratory to attempt to capture the air velocity field around a “Laminar Express” pitch. Nazmus Sakib and Andrew Smith (not pictured) took the measurements. These are our preliminary findings. Continue Reading
How a “Laminar Express” Might Work Post #10
NOTE: The conclusions drawn in this post are based on an erroneous idea about the orientation of this pitch. For the correct ball orientation, this description does not make sense. For a better explanation, see the new post Before I get started, first I want to acknowledge the influence or Rod Cross’ article on this topic. He Continue Reading
Attempt using a machine Post #3
The point here is that, when spinning on the same axis and no gyro, there is no difference between a 2-seam and 4-seam pitch.
