Portable real-time polarimeter for partially and fully polarized light.

We present a portable polarimeter capable of real-time visualization of partial and fully polarized light over a broad band of wavelengths. Our system utilizes a Raspberry Pi computer with a low-cost data acquisition "HAT" and an integrated photodetection circuit. Wide bandwidth operation is achieved through digital calibration of an arbitrary retardance waveplate presented herein.

However, evidence of tangible decarbonisation is limited. Here we identify precarious differences between the scientific origin of NZE and its social representation in the wider public and explore the consequences of the resulting science-action gap for achieving global climate goals.
