For pilots who fly with both propellers and physics equations

Product Description

Navigate the skies with scientific swagger in our "Acceleration Sensors in FPV Drones Detect Acceleration Via Einstein's Equivalence Principle" t-shirt! This cosmic tribute to drone technology proves you're not just a pilot—you're a flying physicist.

The eye-catching design features a stylized drone silhouette over a starburst pattern, with the scientific revelation radiating around it like the wisdom of the ancients (if the ancients had access to 3-axis gyroscopes and real-time telemetry). The bold yellow and blue color scheme ensures other drone enthusiasts will spot you from at least 400 feet away—the legal maximum altitude for your quadcopter.

This shirt explains the actual scientific principle behind how your drone knows which way is up, something most pilots understand about as well as they understand their drone's warranty terms (until they need them).

The Backstory

This design brilliantly highlights Einstein's Equivalence Principle—the foundation of general relativity that states inertial mass and gravitational mass are identical, making acceleration indistinguishable from gravity. In practical terms, this explains why your drone's flight controller can't tell the difference between tilting and accelerating, requiring both accelerometers and gyroscopes to maintain stable flight.

The starry background represents both the scientific brilliance behind modern drones and the night sky you'll likely crash into if you ignore these principles. The dramatic typography mimics vintage sci-fi posters, suggesting that today's drone technology would have been considered pure fantasy just decades ago.

Perfect For:
-FPV pilots who can explain roll, pitch, and yaw while completely disoriented
-Engineers who understand their drone's IMU better than their own inner ear
-Physics enthusiasts who fly drones to demonstrate scientific principles (and definitely not just to have fun)
-Anyone who's crashed enough drones to develop an intuitive understanding of Einstein's theories

Product Details:
-Made from cotton that obeys all the laws of physics, unlike your flight footage claims on social media
-Machine washable (more reliable than your drone's return-to-home function)
-Available in sizes S-XXL, accounting for pilots of every gravitational mass
