What if you had a perfect digital copy of yourself? A virtual twin that could test medications, predict health issues, and optimize your life—all without risk to the real you.
Digital twins are virtual replicas of physical objects, systems, or even people. And they’re being used to revolutionize everything from manufacturing to medicine.

🔬 What Are Digital Twins?
Definition: A digital twin is a virtual model that mirrors a physical object or system in real-time.
Components:
1. Physical object (car, person, city)
2. Sensors (collect real-time data)
3. Digital model (virtual replica)
4. AI/simulation (predicts behavior)
The connection: Continuous data flow between physical and digital.
