Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.

- ‘The trajectory is the path traced by the center of gravity of the projectile from the origin to the level point.’
- ‘After all, we still use Newton's law of gravitation to explain and predict the trajectories of projectiles, even though it is no longer believed to be strictly true.’
- ‘A guided missile corrects its trajectory as it flies, homing in, say, on the heat of a jet plane's exhaust.’
- ‘As supply meets demand, a future is created, independent of any plan, but revealed in the trajectories of market forces.’
- ‘The reaction paths are five-dimensional trajectories that cannot be summarized in a single picture.’
- ‘A few years ago, my playing partner hit a drive which had the trajectory of an Exocet missile.’
- ‘The dust trails spread out over time as each particle continues to orbit the Sun on a trajectory similar to the path of the parent comet.’
- ‘A talk on an Air Force rocket-fuel project set their own research trajectories in a new direction.’
- ‘Turning toward the central piece I choose a path defined by the trajectory of a rail leading to the center.’
- ‘At this time ideas of the trajectory taken by a projectile were still dominated by Aristotle's thinking.’
- ‘Since then it has been on an upward trajectory and now stands at over 20 per cent.’
- ‘Among lawful sequences of events are Galileo's laws of free fall and the parabolic trajectory of projectiles.’
- ‘The ball soared in the azure sky like a missile with a perfect trajectory and rolled a lot upon landing.’
- ‘A ray path is the trajectory that a small packet of seismic energy follows as it travels through the Earth.’
- ‘I can also move things through the dome by drawing paths through trajectories - it's limitless what you can do.’
- ‘Suborbital paths are the trajectories of choice for ballistic missiles.’
- ‘Mortars are ballistic weapons that have projectile trajectories undistorted by rocket engine or guidance system.’
- ‘Then the viewer sees some object describe a trajectory down from the ridge where the camera is.’
- ‘By 1604 he concluded that projectiles travel along parabolic trajectories.’
- ‘In this study, these themes describe common decision trajectories.’
A curve or surface cutting a family of curves or surfaces at a constant angle.
- ‘These three trajectories are known as conic sections, as they are also the curves produced by cutting a cone along different planes.’
- ‘To investigate this possibility, a simple system can be designed to generate drip trajectories where the degree of chaos can be tuned.’
- ‘The thick line is a calculated trajectory near a surface and the thin line is a trajectory far from any surface.’
- ‘So now, you have an intersecting curvature, at every point, say, along a trajectory.’
- ‘Thus, large interception errors were only found for ball trajectories ending relatively far from one's midline.’
