# Glass transitions may be similar in 2 and 3 dimensions, after all

## TL;DR

This paper comments on recent experimental findings suggesting that the nature of glass transitions may be similar in two and three dimensions, challenging previous assumptions about dimensional effects in glass physics.

## Contribution

It provides a critical analysis of recent experimental results, proposing that glass transitions could be fundamentally similar across different spatial dimensions.

## Key findings

- Recent experiments support similar glass transition behavior in 2D and 3D.
- Long wavelength fluctuations may not be as distinct between 2D and 3D glasses as previously thought.
- Dimensionality might play a lesser role in glass transition phenomena than assumed.

## Abstract

This is a commentary on two recent experimental papers in PNAS by Vivek et al. and Illing et al. that convincingly address an issue at the junction of two fundamental questions in glass physics: the role of the dimensionality of space on the glass transition and the possible existence of long wavelength fluctuations in two-dimensional amorphous solids.
